I believe the Hawthorne district is one the best areas in Portland. It has some of the best shopping, great food, and you never have to walk too far for any of it. Not too busy but still enough muggles to make getting this cache a little difficult. Weekends will be worse.
The cache is connected to the bush by a retractable lanyard so don't pull too hard. It is a little low but not too low. There's an open side at the end of the bush where the inner branches are exposed. If I were you I'd look from that end.
