What did you learn about your neighbourhood when you went around submitting portal candidates?
I asked this on reddit some time back, but I'm interested in hearing from more people.
For me, I discovered there were lots of parks with high quality POIs but no Portals. In particular, there were more education signs than I was expecting at the parks too. Learned different things while submitting.
I also learned that just because one park has plenty of portals while other nearby parks don't doesn't mean those parks don't have good POIs. It likely meant no one submitted them.
