My first rainy commute, just a drizzle really, but I was thankful for the showers at work, because at the end I had road grime caked on my shins. 3/4 MTB quick release (zefal) fenders acutally did a pretty nice job, just have to be careful to keep the feet in a 3/9 o'clock position so I don't get water off the rear fender.

Really a pleasant commute, the rain makes people drive slower around here, for some reason... or at least they were giving me more space... kind of nice!
