Yeah, their webs are pretty distinctive. Besides wood piles, I've found them in brick piles and folded up shade umbrellas a lot. They seem to enjoy materials that can hold moisture without quite reaching the levels of "damp". Biggest I ever saw was in an umbrella while I was de-winterizing the pool that I worked summers at. Was absentmindedly going down the rows, opening up umbrellas when I happened to look up and shrieked. Thing's abdomen had to be at least an inch, maybe an inch and a half. The pool manager (70 yo CA native, so seen his fair share) thought I was exaggerating until he walked over and said it was the biggest he'd ever seen, too.
