035 Nevada is where i seen the biggets one i have ever ran across.
67 in Wyoming last year, i went up for a few days of bowhunting and had encounters every day.
the worst was a few years ago rock chuck hunting in southern Idaho. i left the truck just at daylight and hiked up a rocky hill to some rimrock out croppings.(been there many times) spent a few hours shooting chucks, and on the way down the hill, OMG, i took the same route i did up, but they were awake now! i must have been close to a den, i shot 7 that day, and that was just the ones in my path, they were buzzing EVERYWHERE! i was very glad to get back to the truck.to make it worse, i was wearing shorts and tenny runners!i knew this area well, and knew it held alot of rattesnakes, but i have never had an encounter like that.
