All right, I'm finally putting this together.
So the Warehouse Rock Gym is an indoor rock climbing place with a bunch of walls for both belaying and bouldering. What are belaying and bouldering, I assume you ask? Belaying is when you climb with a harness and rope, and you have a partner on the ground to take up the slack as you go up. There's a safety catch attached to the rope and to your partner's harness, so even if you fall when they're not really ready for it, you still won't hit the ground. It's also set up to take a lot of the weight off the person on the floor, so it doesn't really matter who's heavier or how strong you are. Bouldering is climbing without a harness or rope or partner, because you're climbing on walls that are a lot lower.
It's $12 for a day pass, $5 to rent climbing shoes, and $8 to rent the shoes and the equipment for belaying. You don't have to wear climbing shoes though, so the cost is basically $12-20, depending on what you want to do.
One thing that's good to know about the place: It's connected to Alpine Experience, and that's the sign you'll be looking for from the road. The actual door to Warehouse Rock Gym is around the corner on the side of the building.
