Maybe it's something other people have seen already but it was new to me...I didn't get a pic of it though.
Standing in the checkout line, snapping pic of someones legs would be serious creepy.
Anyway, this guy was standing in line at the grocery store ( Incidentally, I was picking up a 6pack of Dogfish 60 IPA...) and he had tattoo's on his calves..at first I couldn't make out what they were, but they were fresh.
Turns out they were pistons...So I asked the guy if he was a cyclist. He said no a runner. But it was really cool.
