I *hate* the sweaty backpack thing, so for all my rides of more than a couple miles, I've got my fredly homemade trunk on one of my road bikes and
the backback sitting on the front rack on my mountain bike.

I couldn't get photos up on this thread for some reason, they both went up ok on the DIY thread a week or two ago: http://www.bikeforums.net/showthread...DIY-Gear/page2
