Ann Arbor Pokemon Go

Here's the best walking circuit I've found, which will get you 2-3 gyms and 13 stops per brisk 5 minute loop (up to 180 spins per hour, for around 600 items). Start at Main and Washington, head south down main to Liberty, turn left and walk to 5th, then turn left and walk to Washington, then back to the start. The stops at Washington and 5th are a little tricky, but I'm able to reliably hit all three without leaving the corner. Same for History of Drinking - it might be worth waiting a second on that corner if you're gold there and have team control. This also has the advantage of being fairly efficient for distance tracking, since there are a lot of straight lines.

Want a prettier and quieter grind with no street crossings? Head on over to the central campus diag and follow this path. This will get you 13-14 spins per loop (~160 spins per hour).

Here's a circuit on central campus (Diag / Ingalls Mall) which will get you 26 stops every 5 minutes of easy biking (31 with the green add-on paths). That's a whopping 312-372 stops per hour, getting you 1,000-1,200 items. It's a little over 1km, there are minimal road crossings, and as long as you don't hit a class change, it's very easy to get around the students. There are also tons of natural spawns for you to grab along the way. The only downside to this path is that you'll be picking up so many items that you'll be dumping stuff by the hundreds to free up bag space! It's also shaped like a bird-dog, which is sorta cool, I guess.

Car grinding sucks. It can be dangerous, it wastes gas, and it kills the whole point of the game: get out and get some exercise and fresh air. That said, I know it's pretty common, so I'll stop preaching and share what's probably one of the easier, safer, and more productive circuits in the area: UM central campus. There's a giant caveat with this: don't try this during peak college traffic times!

Here's one from an anonymous contributor for those of you near Plymouth. The main circuit is the solid lines, the dotted lines are side trips for if you're going too fast and end up chasing your tail.
