Admit it. You've always kinda wanted to poke people with swords. Shoot them with paintballs. And you've always wanted to be like Mike, er... Tyson. And yeah, you've also wanted to hang 60 feet in the air, suspended by a rope and an uncomfortable harness. Maybe it's time for to venture on the funkier side of Boston's indoor sporting game, from skates to boxing gloves; from swords to golf clubs. Just make sure to bring a helmet.
