We visited the Maritime Museum in Manitowoc, which included climbing through a WWII submarine.
We visited the Experimental Aircraft Association Museum in Oshkosh, missing 10,000 Boy Scouts by one day. Whew!
And we just hung out at the house.
If you get thrown from a horse, you have to get up and get back on, unless you landed on a cactus; then you have to roll around and scream in pain.
