Converted our garage for winter sports prep - worth it?

My 13yo is really into skateboarding and needs a place to practice during winter when the weather sucks. So I cleared out the garage, put some rolled rubber flooring down, set up some DIY ramps and boxes. Cost me like $400 total and probably 8 hours of work but honestly? He's actually using it. Not out in the cold, easier for me to keep an eye on, and he's invited a couple friends over to practice. If you have a kid into board sports and live somewhere with rough winters this might be worth considering. Happy to answer questions if anyone wants to do something similar.
