Riiiiiiiiiiiiiiiiight.....
I was just playin around man....My thighs are WHIIIIIIIITE so I always gotta have shorts on down to my knees. My knees are even pretty white compared to my calves and shins too. I was out in the sun for about 8 1/2 hours per day for 5 days straight a few weeks ago at football camp wearing full pads. My lower legs got nice and dark, but that's it!
And no, I don't pull up my shorts when I tan at the beach. Actually, I don't tan at the beach, I don't even tan at all! I just work outside all day and usually don't have a shirt on...
