I'm pretty paranoid of snakes now when fishing, especially brookie streams. About 3 years ago, me and my brother dId a 2 night backpacking trip in a wild area in Sproul sf. During our hike out, we were both constantly looking ahead on the trail for snakes (we saw a rattler during the hIke in). On the way out, we rounded a corner on the trail to a particular scenic section (small stream w/ short waterfalls, moss everywhere, steep terrain etc., just beautiful) and I briefly lost my focus on the trail ahead. Just seconds after that, I heard my brother yell behind me. It startled me, and I jumped backwards, thinking there was a snake in front of me. As it turns out, my brother yelled after I had already stepped over the snake, and when I jumped backwards, I literally hopped back over it. When I looked back, I saw a large rattler coiled up on the trail, roughly 6 inches in diameter and 6 feet long. My brother looked like he saw a ghost. He said I literally stepped directly over it, and then jumped back over it again.
