I took my bike in for a tune-up Thursday and I'm not getting my Trek back until Wednesday. Aaurgh! So in the 1-2 hours I spend every day on my bike, instead I'm sleeping in, reading the paper, watching television ... and essentially going stir-crazy in the meantime.

I never thought it would be like this, but in the past three days I haven't slept well, I've been super-edgy and the lack of exercise has affected me.

So what do I do until Wednesday, as far as that release? And as far as maintenance, should I learn how to tune up my own bike, or leave it to the pros and face a week's worth of serious withdrawl?
