I spotted this sign at a rest area near Phoenix, Arizona. Anyone who knows me will tell you the only thing I hate more than a snake is a scorpion. When I lived in Panama I had a couple near misses with them. It still gives me shivers to even think about it! ACK! I read once that a black florescent light would make a scorpion glow in the dark. I was creeped out enough a couple times that I actually bought a battery powered, hand held black light. A few times I lurked around the house with my light checking doors, windows and floors to see if I could spot any of the little devils glowing but never did. The heart attach I would have had if I did would have REALLY been dangerous!
