Legend Days in the fall are terrific. Activities for kids of all ages and the tour is awesome.
A fun tour...ESP during headless horseman season
Interesting stories on the tour: Irving would have 7 hour dinners. He expected lively discussion, but no religion or politics.

Bring you own water when it's hot.
