I'm with Irulan and Denise on this one--I'm sort of proud of my biker tan. Makes me look like a 'real' cyclist! I always use sunscreen but still get the lines, of course. I especially like the little round brown circles I get on the backs of my hands from the holes in my gloves.

P.S. I can vouch for the effectiveness of gloves in a crash. I highly recommend wearing gloves if you can.
