There's no better time to head out to what a lot of Milwaukeeans used to simply call "Wood, Wisconsin," for a tour of the grounds. Best of all, you can go anytime and the tour is free, if you have an Android or iPhone. That's because there's a walking tour app - which just may be the first of its kind in the state - that you can download free and use as an audio tour and map to the sprawling 90-acre grounds.
