We had a ton of Founders in our area, so it is definitely rich with great portals. Not only in a quantity level, but the quality of the portals is also nice with accurate historical descriptions and names. I've heard in other places of the country/world it isn't always as nicely done. I learned so much about the town I moved to all by playing Ingress, and I'm so thankful for that info.
"Oh woah, you mean the Bio Studies place used to be the first schoolhouse in the County? That's pretty cool." Kind of stuff.
"Oh woah, where we crossed these railroad tracks right there is actually where soldiers crossed during Zagonyi's Charge during the US Civil War."
So true. We learned quite a bit about or town as well. We actually only noticed a couple landmarks that weren't properly identified. It happens though.
