No hiking = no snakes, but if you go hiking, you're going to see them. I usually wear long pants with loose pant legs. Supposedly that makes it a little harder for them to bite. I also usually wear high tops when on XC hikes and also on backpack trips.
Snakes are typically reticent to strike -- they need that venom for things to eat and don't want to waste it on you. When I was stationed by the Army in AZ, I frequently saw multiple rattlers
per hike!
I even had my face right in front of one when I was pulling my self up to a small ledge. LOL, that was a tense moment. That was a really quick downclimb!!
I also stepped one time over what I thought was a stick. It coiled up and rattled. Yoiks!
Still, despite all my close encounters with snakes, I've never been bitten. Be careful out there, but don't be too paranoid about snakes.
If you were really worried about it, you could get some snake chaps. Most snake chaps are so stiff that you don't want to hike in them. Usually just keeping your eyes open and being aware of your surroundings is enough.
Hey Zip!, didn't you one time post that you had found some snake chaps that actually could be hiked in? What brand were those and where did you get them?
