I am in college now. I went to the Air Force first and now that I am a civilian again I have the opportunity to go to college. Here is what I do to stay in touch with moto as well as some things I know that others do. Me personally I got a storage unit and I keep my bike down here with me. I only get to ride a half dozen times a year now but I still get to ride. I help out at a track, find one that is close by and tell them your situation. They may pay you to help they may not, I don't get paid but for me to be out there running equipment, helping on race day with various tasks is really something that is therapeutic to me. I enjoy it and I get to ride there whenever I have free time. There are a couple of things I would warn you about if you get a storage unit and bring your bike. 1: School comes first, tone your riding down, I have been broken twice now since in school and it really takes a toll on the GPA, it is hard to get up when you are in pain and get to class. 2: Find a secure storage area, one in a good area with a fence, double lock your units door with shrouded locks, get a long locking cable from harbor freight put it through your frame and both wheels as well as through some heavy stuff like cinder blocks, semi rims anything with weight that is awkward. Just make it difficult to take. 3: Get insurance on your bike for theft, mine costs under 100 a year. Not that it is likely to get stolen but you will not be there to check on it everyday so play it sale.
I have a buddy who absolutely could not take his bike. He bought a good DSLR camera and goes around to the races every weekend and takes pictures of everybody and posts them up online. They are free to everyone and everyone around the tracks knows him, loves him and he always gets in for free. He is very plugged in.
I hope this helps good luck at school.
