Start greasing those wheels and decorating those beds for the Charleston Bed Race to benefit Camp Happy Days. Five-person teams will duke it out in a two-block, one-on-one — or bed-on-bed — race, with eliminations after each round. The reigning champion will take home gloating privileges and the joy of having raised money for kids with cancer while riding a crazily decorated bed through one of downtown Charleston’s biggest parks. If you’re still struggling to gather four friends to join you, you’ve got till the day of the race — just bring your racing bed and you can sign up on-site. Spectators and competitors alike will love wandering the beer garden, and there will be food from Cast Iron Catering and Kickin’ Chicken. 100 percent of the proceeds will go to Camp Happy Days.
