I have a 150 acre farm, creek and 1865 era farmhouse. Over half is in woods.
If you just walk around, fish in the pond and go into the old buildings you will run into a rattlesnake about twice a year.
If you look around for snakes we can find a rattlesnake a day sometimes more.
I killed 3 Canebrake/ Timber rattlers that crawled out from under the farmhouse one at a time while i worked on the tractor. They were young but around the house with dogs and kids around we get rid of them.
If i see a snake before i get too close to it, outside striking range i am cool but if it suprises me and close i still jump.
We have killed a few rattlers at 6 ft+ over the years. The wife skinned out one that was 6' 4" and 13 rattles.
