You catch a glimpse of Bigfoot

Its a shitty day today. Unexpected cold as swept across the mountains and you are under-dressed to be out in the wilderness. You caught poison sumac and you itch like crazy. To top things off when you woke up this morning and took a piss, there was blood in your urine. The only plus is you find another set of big foot tracks and you pad along following them. You catch a quick glimpse of a gigantic ape like creature walking through the woods on its hind legs. Just a glimpse, but its like walking into another world!
