Sellwood Riverfront Park is an open dog run park, with a great walking path around it, that features more than half a dozen Pokestops know for dispensing a high rate of various balls. Oh, and it’s the local nesting place for Pikachu. What do I mean by nest? I mean you can very likely catch 4 of a specific but uncommon Pokemon in a 60 minute period. That is what I mean by a nest.
