We have made several trips there, and DH took a woodworking class. It was interesting to "watch" his attitude. At first, he was very excited, then annoyed when he found out how long the day/class was. But in the end, the class was (supposed to be) long over, and he was still in there working away on his project. Definitely a paradigm shifter.
Personally, for me, every trip involves a bowl of the sweet potato/jalapeno soup in the cafe.
One thing I highly recommend: some days, there is a hay ride farther into the property. We've done it twice, and I'll do it again as many times as possible. The ride and views are nice, but what's priceless (to me) is the sharing from the folks who drive the horses and narrate the tour. On our two rides, we had two different gentlemen who shared very different things about the community and their activities.
I also always get a kick out of the garden -- it's really a sort of demonstration/experimental garden (I can't recall what they call it). Behind the big red barn where they give classes. Anyway, every time we go, it has different things planted in different stages. Living in the same growing zone, I've found it very informative on every visit.
