Heh, I keep it in my house (its an A-Frame), and when I ride it to campus I lock it up. I have a cheap lock too, not cheap enough that simple bolt cutters could break, but cheap enough that an expierenced theft could get around in less than a minute. *just try to remember to lock it up next to a more expensive bike*
Hehe, I need a bike for long distances. Seems I wont be getting one soon though since I will be going to Florida for a week July 6th-13th, and then building a new PC sometime soon after.
On that note, it's a good idea to replace the seat and wheel quick-releases with something harder to remove.
I run my chain through my wheels and frame, and then usually take the seat into class with me. Yeh it looks wierd carrying a seat around, but not as wierd as riding a bike without a seat.
