Ok, that calls for a totally different answer, We did a hay ride one year and the best scare, which suprised me because I thought everyone would get it as Jeepers Creepers was big that year, we had a row of scarecrows and the last one was a live one dressed like JC guy with an ugly mask jumped down just when the ride rolled by and he jumped into the wagon with them. The screams were beautiful. Another one, there is a light pole along the trail but a tree would work, we had a truck next to it like it had hit the pole (put the hood up, etc.) the first thing they saw was a little kid holding a ballon just kicking his feet as he sat on the tail-gate, just a little blood around his mouth, then the ride past on and we had a dead body hanging out the truck window, blood dripping down the side of the door he was hanging out of, and a clown sitting on the hood with a butcher knife. Got good reviews on that. We also had 3 witches around a fire in a large cauldron with little kids in cages screaming for someone to help them and let them out. Just a few of some of the things we did. A hay ride is hard because you can only use open sites so you have to really be creative on your scares. Good luck, let me know what you decide to do at each site. I would be very curious as we may do hay ride again next year.
