Here's what I came up with:
Sports equipment organization
If you have exposed studs in your garage, this is a great way to organize stuff. Otherwise, you can build shelves or put in hooks. I looked around and found a couple interesting ways others have organized their sports stuff.
This is a neat idea from www.cleanandscentsible.com.
These Kobalt organization rails also look interesting.
More sports organization
I couldn't help including this picture - for a bit of a higher budget, this looks nice!
