Replying to Staying good during summer

My last day of skiing was a couple days ago and I progressed a lot! I am really bummed about having to start all over again next season with learning the tricks I got down this year, and was wondering what you guys do in the off season to maintain your skill. I was thinking about getting a pair of cheap in line skates and riding around and waxing curbs to grind on and shit like that . Building a backyard setup would be tough, and my backyard is pretty much just flat anyways. What you guys do during the off season, or any advice for me is appreciated thanks
