There definately thick in Oklahoma, came close to stepping on one last September while checking a feeder shortly after dark. But at least you can hear rattlesnakes, it's them copperheads that people fear the most. Them dudes are aggressive, knew a lady working in her garden, got bit three times by one copperhead before she knew what happened.
+1 I live in Oklahoma and I have seen a few while scouting during the summer months. I am going to buy a good pair of snake books this time.
