When living stateside in my early 20’s, I’d often catch an after work ride in the East Bay Area of San Frasisco.
Once, ridining with a friend I was heading down a fire road and had to stop and wait for her to tell me directions. I was looking at the amazing view of the sea, then looked down at the ground to see that I had pulled up right on the middle of some kind of Tarantula migration across the trail. They were crawling on my shoes, over my front wheel between my spokes and right in front of the bike.
I wasnt sure sure how to ride away without squashing them, or flicking them up from the wheels.
Im not an Arachnophobe, but they were the size of my hands and it gave me the fear.
Unable to do much else I just let the crawl over my shoes and watched.
