Gas-powered cars will soon be replaced by electric cars, which will be replaced by two-person motorcycles powered by nightmares. Catch some combustion-engine action while you can with today's Groupon to North Star Speedway in Palmer. Each ticket is for the speedway's general bleacher seating, and valid for any race during the 2011 season. Though the general gates open at 4 p.m., the pit gate opens at 1 p.m. and hot laps run from 2 p.m. to 3:45 p.m. Choose between the following options:

• For $10, you get two adult tickets (up to a $20 value).
• For $20, you get two pit passes (up to a $40 value).

North Star Speedway's circular asphalt track plays host to six classes of race cars, including Bandoleros, late models, Legends, and Baby Grands, which are two-thirds the size of normal stockcars. Adult tickets give admission to all the racing action, and pit-pass brandishers can enter the bustling race grounds and walk among the drivers and crew in hopes of snapping photographs and trading stories about using engine oil to soften callouses. While waiting for the green light, children can swing and skip at the speedway's playground and entire families can grab snacks and treats at the snack bar (not included in this Groupon).
