Anyone else been to Vertical Ventures Indoor Rock-climbing Gym? It's in Tampa off Anderson, just north of Sligh.
I've been three times in the past two weeks and have to say that it is an excellent complimentary activity to mountain-biking. It gives mostly an upper-body workout, but since the resistance is your own body-weight instead of free-weights, you won't become Mr. Ape-man from it.
I was hoping we could get together some SWAMPers and go the first Friday night after New Years. They're open until mid-night on Fridays, and it's 50% off. Should cost under $20 per person
