Looking around the Ingress Portland Or. map it seems like Ingress will take you on an extensive tour of Portland's least valuable resource, multicultural pro-vegetable mural projects. I don't hate on these murals but omg there are about a billion of them in this town. At least ten within an easy walk from my house. All the same pretty sure I've got to give it a try and burn out in a week just like every other multi-player game that you need to put exhaustive work into to achieve any kind of excellence.
In order to get a certain trophy, you must submit a certain number of new portals. In order to level beyond 8, you must have certain trophies. Result: shitty public art projects becoming portals. Portals everywhere. At least, where you can drive. On my entire 12-mile standard bike ride, which is entirely on the ocean, there are three. Why? Can't drive there. The playground mentioned above is filled with whimsical bird houses. Each one of them is a portal. You walk it as a loop and level up. Or, go through and blow it up. Funny thing is, the dude who nuked mine was probably in plain view but I never saw him and he never saw me 'cuz our faces were buried in our phones.
