While researching and compiling our book, "Tombstones of Cannon Co., TN." I never encountered the 1st snake of any kind, in Cannon Co. We walked through woods, rocks, and underbrush, in all seasons, for several years, without any problem. I do wear boots and make a lot of noise. Just dumb, rookie luck, I guess, but I believe that most snakes are probably as scared of people as people are scared of snakes. I don't think they really want a confrontation. Besides, the vast majority of better known cemeteries in Cannon Co., are pretty well kept. Many are mowed frequently, in the summer. So, I wouldn't let a snake alarm keep me away, if I wanted to do research in the county. I have had far more encounters with ticks, than anything else. Load up on "Deep Woods OFF", or even the Avon product, "skin so soft"and you should be OK. Jess Lewis
