I'm with you rough - I am very proud of my tan lines too - for other people who cycle, they see my brown arms and pale hands and they know I cycle too - its like a badge or password into an elite club - no matter that I'm really at the beginners end of the spectrum. I bike, and I bike enough to sport these special marks, so I belong!

And when the uninitiated ask why I have have such interesting tan lines... well its a legit excuse/reason to brag about cycling!
