I've seen pit garages with a pole rack built in (basically just a couple of bars hanging from wires attached to the roof.
We have one like that at my high school...it's nice since we can arrange the poles by height (one section for 11' poles, another for 12', etc.) so that it is really easy to find poles when you need to use them. It's also nice to just be able to roll it on and off the pit setup and a great protector against the weather.
