Creed's top recommendation for Halloween activities is Barnyard Boo at Thanksgiving Point (not to be confused with the much scarier Cornbelly's Corn Maze next door, which looks like it would be fun for much older kids). Barnyard Boo is at the "farm" and I have to say this fake farm is my favorite. The animals are all so clean and fluffy and friendly (what can I say, I've become quite the city girl). $7 buys your child a punch pass to participate in seven activities of their choosing. Creed went for the Ring Toss, Ghost Bowling, cookie decorating, face painting, and wagon ride around the farm, and two pony rides. He really loved those ponies (or to be more precise, the smallest pony, he wouldn't go near the rest)
Tip: If you go next year, be aware that it's only open on weekends and Monday nights. I heard that it can be crowded, but we went on a Monday night and never had to wait in line for anything.
