Things to Do in Randallstown

S.J. Koch Duffy's electric boats are eco-conscious, as they don't burn any fuel. Emitting zero emissions, the 22- and 18-foot rental boats provide breathtaking views upon departure from any of the company's two regional watery locales. Based on the harbor of choice, renters can take the canopied vessels floating by Annapolis's US Naval Academy, along the waterfront restaurants of Baltimore's Inner Harbor. On board, a built-in stereo system emits an energetic score to each renter's adventure. Duffy's website claims the boats are as easy to drive as a golf cart, but also offers training for new drivers. Self-propelled adventures are also popular, as the company also rents paddleboats and kayaks.

Although tape and video media were once the mainstays of recording technology, repeated usage will gradually deteriorate their quality. The team at Advanced Video Systems has stymied that deterioration by digitizing Super 8, 16mm, audio, and other media into wear-proof CDs and DVDs for more than three decades. In addition to preserving precious memories, the staff also restores the color and contrast to faded and foggy images, slides, and vinyl records.

Even as a flight attendant and marketing salesperson, Belinda Magruder never forgot her younger years as a crewmember aboard international sailing charters. The freedom of clinging to the wind as the boat raced across open waters continued to call to her, and one day she got an opportunity to go back. After a chance ad for a marketing position led Belinda to work for Getaway Sailing, she eventually took over the company. Since then, Belinda has filled Getaway Sailing's school with American Sailing Association–certified instructors, many of whom were raised on the bay and grew up manning the rigging of their families' ships. Some of the school's captains hold merchant mariner's licenses and boast year-round experience in running freighters via tugboat or beating Poseidon in weekend poker games.

A fleet of 17 boats at lengths of up to 35 feet conveys passengers through classes covering navigation and cruising, as well as certification courses and team-building trips. With the water gently patting hulls, boats cut through the sunshine and across the Inner Harbor or to the Francis Scott Key Bridge on day charters, or take longer trips to farther-flung stretches of aquamarine around Rockhall, Oxford, and St. Michaels. Evening races let larger boats jockey competitively with snails snapping a staccato rhythm against the darkening sky, and harbor sails put small groups out with a skipper, leaving them free to bar-hop or heckle passing schools of fish. Getaway Sailing's instructors immerse their students in the insular sailing world and have drawn members from as far as Hershey, including patrons who have volunteered to help staff the school's booth at boating trade shows.

That Bounce Place enthralls energetic tykes with more than 13,000 square feet of space brimming with bouncy attractions and abundant games and activities. Feet shielded by mandatory socks launch into the air on bouncers, obstacle courses challenge puzzle-solving capacities, and a massive inflatable slide challenges Olympic luge records. A big-screen television broadcasts favorite shows, an air-hockey table officiates competitions with puck-smacking peers, and complimentary WiFi enables guardians to relax while their children play. An exclusive toddler arena opens the gates to its age-appropriate toys only for those who know the secret abridged version of the ABCs. That Bounce Place's party packages simplify birthday planning with perks such as time in a private room, party supplies, and pizza.

A phosphorescent Frankenstein stands guard over a legion of glowing ghouls that loom throughout the black-lit corridors of Monster Mini Golf's 18-hole course. Framed by neon-green rails, the course's pitch black putting surfaces give the impression that luminescent orbs are either somersaulting in far-reaching pockets of space or rolling across the darkened cellar of your boss's punishment office, a murky abyss populated only by gothic tropes and the presumably undead. A live DJ soundtracks each birdie-hunting expedition with bone-chilling beats as players read putts or meander around the flashing lights of the adjacent arcade, where guests can wager a month's rent in games such as skee ball, air hockey, and Guitar Hero.

Monumental Helicopters’ fleet of choppers offers clientele breath-nabbing views of eastern Maryland and the sea beyond. The compact R44 Clipper comes equipped with floats for water landings into arch nemeses' swimming pools. The aircrafts’ routes fly around Baltimore, taking in the city's sites. Though not included in this Groupon, tours also zigzag between Baltimore, Washington, and Annapolis and even embark on custom tours that soar anywhere within 25 miles of Haysfield Airport.
