In 1891, James Naismith mounted two peach baskets on opposite walls of a gym, inventing the rudimentary version of what we know today as “shelving.” Take your basketball off this grand innovation with today’s Groupon: for $70, you get one team registration to the BAM Jam basketball tournament on August 5–6 (up to a $140 value). Teams must be registered online by July 26, when this Groupon expires.
With proceeds benefiting the Boys & Girls Club and Idaho Select Player's Fund, BAM Jam incites three-on-three hoop wars between players of all ages and skill levels, with 142 teams playing on 22 courts its first year alone. Grab two buddies or half an octopus and take part as downtown Boise transforms into an eight-block, multicourt labyrinth of bracketed competitions, with divisions designed to evenly match third-grade female dribblers, men older than 40, teenagers older than 20, and elite adult and high-school players as all vie for netted glory. With a guaranteed minimum of three games per team, even ragtag Lilliputian trios can pursue quixotic competition in the city streets—all under the keen eye of the BAM Jam monitors, who keep conduct sportsmanlike and mischievous backboards from wandering off to the concession stand midgame.
