House on the Rock
After we visited the Cave of the Mounds, we checked out the House on the Rock, which was very cool in a different way. For anyone visiting the House on the Rock, I recommend taking 2 days to go through the whole thing. We decided to tackle it all at once, and it was a bit overwhelming. The guy who built the house was an extreme collector (do I hear pack rat?) and going through it was akin to entering a different dimension. It simply boggles the mind.
