Same here, unless I'm going on longish (40-50 miles) rides, and even then, I just have a couple of old pairs of biking shorts from my tri days. For commuting/utility riding, I don't need the bother and while I'm pretty much each to his own, it seems like some of the people I see on my commute are a little bought into the whole "buycycling" concept, which I admittedly wasn't immune to in years past.

But they probably think I'm the King of the Freds (or a DUI convict) in my jeans/shorts, boat shoes, t shirt tootling along with friction shifters, etc.
