I have been fascinated with pholcidae my entire life on the west coast because every house i've ever been in has been inhabited peacefully by them.
when I go to the east coast i'm always trying to find opiliones to look at knowing that they're the 'regional daddies', but i've never been successful finding one.
At this point I just presume either they're a bit more rare, or everyone on the east coast keeps tidier attics/crawl-spaces.
