We've climbed wooden ladders up into dark spaces to reach the top of the St. Josaphat dome and walked countless spiral staircase to get to the peak of the City Hall tower.

We spied 32-year-old Lenny and Squiggy graffiti scrawled into the bricks backstage at The Pabst and we've explored boiler rooms in old schools. In a few days you'll read about a visit to the Eschweiler buildings on the County Grounds.

Today, I'm taking a tour of the Milorganite factory, and I've got a few more such visits in the queue, taking you behind the scenes and in rarely seen spaces in Brew City.

Where to next, folks? What do you want to see? Post your suggestions using the talkback feature below and I'll do my best to get to the places you want to peek at.
