We also came across a timber rattler last year while planting our food plots. We left the shotgun in the car so the guy that plants out plots killed it with a machete....there was no way any of us were going to get close enough to kill it with a machete.
To bad the hides got buggered up,there is a sporting goods store over in blountstown who pays for them. 2 or 3 bucks a foot,for the whole snake. I took several over there last time I went to the dentist,made 50 bucks.
