I'll be spending a couple of days in Portland and am wondering if the locals could give me a list of "caches not to miss" while I'm in town. I'm most interested in some fun urban caches downtown. I probably don't want to spend a ton of time on 4 and 5 star toughies, though. But, which ones are the local favorites? Thanks for the help!
