Most things don't bother me. Heights, snakes, close spaces - nothing. Just something about spiders that makes my skin crawl.
I have been walking through corn and soybean fields to come across a large garden spider/garden spider web and walked back out to go back in in another area.
Honestly spiders were a big reason I quit detassling corn for money when I was a kid. I'd paint, bale hay, walk beans, etc but walking right into one of those big webs at 530 in the morning and seeing a spider the size of your head about 5 inches from me was enough for a career change.
