oh man, I hadn't thought of that! there were a couple really large rat snakes dead in the road the last two summers (one each summer) - like 4 or 5 foot guys... I bet that is a big part of the population increase these last couple years! I should put up a snake crossing sign! ha, wonder if they make those... oh nice, seems someone does:

the good news is... I've got a pair of nesting hawks that moved in last year (somewhere in the woods, not the house/attic or anything, thank god!! lol). so maybe some additional death from above action will help out (the owls must be overworked). heh.
and 10x YES, mowing over a snake freaks me out.. but even worse, when I'm cutting around trees... I'm 100% paranoid about snakes overhead - only took one snake in a tree 10 years ago (that I didn't see until I was close enough to be in "oops, landed on you! ssssry!!" range, and I'm perma-freaked when mowing under trees. your pic did not help one bit!! ;) :)
