Make sure you lock it up good! University/college towns are a favorite for bike thieves.
This is a bike you should bring into your home when not riding. A basement, an unused room, or a laundry room are good options. Apartment dwellers without such spaces often bring bikes into their living room. A private locked garage can also be OK.
Use a good quality U-lock - that generally means Kryptonite, On-Guard, or ABUS. Cable locks are real easy to cut, but using one of each type can be a good strategy. Make sure to lock up the frame, rear wheel, and front wheel.
