Where -- Earth Treks Climbing Center, 7125-C Columbia Gateway Drive, Columbia
When -- Tomorrow, 2:30 p.m.-6 p.m.
What now? -- The open climb format allows climbers to pay $5 per climb instead of the usual full-day admission fee. Climbers younger than 18 must have a waiver signed by a parent; it can be printed from the Web site. If watching the Redskins' offense is going to drive you up a wall anyway, maybe you could skip the first half to go climb one.
