Looks like they just went out for a few minutes!

This house has been beautifully restored and really does look as though the Grants will be returning while you are there visiting. The tour guides are very friendly and informative.
The house is a lovely attraction in a perfectly charming town in northwestern Illinois.
The house is maintained by the State of Illinois so it is closed on Mondays and Tuesdays. They ask for a $3 donation...I think it's a very good deal.
