Thanks all!
I am getting the tent! He'll love it!
As for Magic Mom's idea... I will be setting it up in the basement, if I can figure it out

But, even if it takes me a couple days, DH won't know... he doesn't go in the basement, because that is where the laundry room is!
I might also do the
other thing she suggested...
Oh, and the map idea is a great one for the "paper" portion of the gift!
And I see you are in Livonia, so I am assuming you saw it at the Costco at Schoolcraft and Middlebelt! I am calling them now to put one on hold!!!
