You know what I hate? Leading the search for a cache and walking into a faceful of spider webs. That's the danger with this guy.
The cache is close to the dock at 158th & Airport way, where you'll put in and paddle west. Look up for spiders up in the tree branches that overhang the slough.
The location is a new one for this cache--it had to relocate from a previous location to the east because of changes in Portland Parks rules. So there will already be some signatures on the log from before.
