If an aluminum or steel-framed bike, a rear rack and the little clips are definitely the way to go. It's a lot more comfortable to carry the load on your bike than on your back!

Another thought might be a messenger bag... a little more expensive, but maybe more comfortable than a backpack...

Sorry for the delay, I don't have internet at home, so this is the first I'm getting to the replies.

I'll have to look into those clips. The frame is aluminum, so that's definitely an option. But how easy is it to take the rack on and off? I obviously won't want it on the bike when I'm doing a normal ride.

I have a messenger bag, but it's too small to carry all that much. Then again, if I plan ahead and carry things in on a train day, it'll be perfectly fine.

Made it home fine Friday night, it was warm and my shoulders were tired and sore, but I made it. And the car from the local bike shop gave me a friendly honk as he drove by
