We were just there today! It's a lot of fun. The took the BIg Thunder Ranch area and turned it into a Halloween bash. There are a couple different areas. The normal ranch area that is open all year round (with the goats and the house) showcases an awesome pumpkin carver. The log cabin has a really cute decor inside of pumpkin-headed scarecrows having a Western themed Halloween party inside. It's set up with 3-4 different photo ops. The goats are also wearing fashionable Halloween bandanas!
The old BBQ restaurant area (opened only seasonably - with the best kept secret of really nice bathrooms in the back building) is host to Woody's stage show and other family activities. There are picnic benches with baskets of crayons for coloring Halloween activity sheets (get those from the nice CMs there) and also to sit at while decorating the cookies you can get for $6 or so. You get your choice of a bat or pumpkin and it comes with 3 icings, sprinkles, and a sugar face.
We had a blast decorating cookies and doing all of the activities. Spent about an hour there.
