I passed 4 snakes on the trail today.
The first was a big black snake of some sort that seemed docile and didn't care about the passing bikes, and 3 large rattle(?) snakes, which decidedly cared
about the intrusion.
The second encounter was not as unremarkable. I got attacked by one rattleless rattlesnake right before the climb-out on Big Drop today. He was just to the side of the trail and lunged as I rode by. Luckily, he missed me, though I think he bounced off some part of the bike. He was about 4' long and though his tail shook it made no sound. I warned my riding partner who wisely turned around. I got a bunch of pictures of it, then kept riding.
We rode West Meadow and Baby Nessie, then took advantage of the nearly-empty park and rode them "backwards", during which I startled two more snakes. I only heard them slithering away as I passed, but my partner was behind me and saw the last one, which he claims was a 6' rattler.
I thought going tubeless would end my problem with snake bites
