Thanks all. I had had the same thoughts, that I'd likely be replacing much of the same parts on a new bike as well, I just didn't know if the old Trek was even worth putting new money into, KWIM? But I think it will suit my commuter needs just fine, and its probably better to see how commuting goes for a while before I start spending $$ on a new bike. So, I'm taking it in tomorrow for a tune-up and to get street tires. I have a new saddle and pedals on my birthday list (my birthday is in 3 weeks). I'm feeling a little overwhelmed by the pannier/bag options, but there are some great threads on that topic in this forum and I'll figure something out, I'm sure. Thanks for the advice!
