Aw, heck, panniers and that stuff are still piling onto a machine not *really* made for the job. http://www.xtracycle.com/index.php is what I would do :-) (I have the "free radical" on my Giant hybrid and love it... but I would love one fo the Breezers even more, with their weather-resistant setups and dynamo lights and the whole works). They're giving two away with a contest (the Free Radicals, not the whole bikes)
I have to say that I get a little more friendly treatment with mine 'cause I look like I'm a commuter... but people are just friendly here and it's not too busy.
