Bob, and others, that Google was the Oakland County Courthouse complex..go north..13miles...go east, 2 1/4 miles turn right, walk straight until your hat floats....Playhouse is just on the right.
I'll post a picture. It started when my son's "fort" was in the driveway turn around and I told him we needed to move it. I put 4 - 20' long 6x6 posts in the ground in a 7'x 9 "rectangle", more or less. I used the green tractor to lift the posts as they were very heavy, 2 ropes,chains c clamps, a boy, and a girlfiend later they were in. To make a long story shorter, 15 windows on sale/clearance at HD and a sliding door wall later and a pull down attic ladder to the upstairs loft. It looks like the Park Rangers Headquarters, the DNR, as we call it here. The hand rails are the step bumpers off the Sierra pickup, 5' long and chrome plated, turned upside down to hide the step pockets. Clever eh? It was an educational "experience" for me and my son age 11 at the time. We pulled up siding with ropes, nailed and screwed on trim, he learned alot. He has never slept overnight there once! "There's bugs out here, Its too cold, it's too hot".....Kids today have learned how to whine like I can't remember us doing, maybe we were the same.? I'll probably turn it into a "biker" club house or a religious temple , form a church and take a tax write off!Off for now, Bill
