My poor mangled arm

I’ve been camping for a week, and commuting 50 km each way each day in my Datsun Pulsar. It has 2-40 a/c, and now I have an awful burn, just on my left shoulder/upper arm.

Ack, I didn’t think I have to put sun screen on to zip around in my car. I put some afterburn on it, but it’s not helping. Right now I’m sitting infront of my computer twitching like I have a bad case of Turret’s Syndrome. I hate sun burn (It might be wind burn . . . whatever eh?).
