i saw this spider a couple days ago first on farm land, but i am home now (in edmonton, canada) and i saw one just like it, the biggest spider ive seen (ive only saw small ones compared to this, you people probably think this is small too) it is probably like leg span and body about as big as a loonie maybe bigger, with a big fat pooper on it. this bad boy is wild. (note it hardly moves, the one i saw on the farm was in the same spot for hours, maybe he was snoozin) i have two pics, 1 from the top, 1 from the underneath on its web. it reminded me of a crab kinda. and scared me because i hate spiders.
