We go all out for Halloween here. There is a campground with about 150 sites where all the campers decorate. It is near the large city of Little Rock and as such gets a LOT of kids visiting. Lots of fun!
We built a broken pirate ship bow complete with cannons that shoot (fog machine smoke, lights and sound effect). This year adding a ship mid-section with ships wheel and skeleton crew (pun intended). I even go so far as to not shave for a month for effect LOL....
Even with all we do there are some groups that have even larger setups. One group actually built a good-sized haunted house out of several canopies and tarps. Complete with the classic operating room and the chainsaw scenes...Amazingly it all goes up in one and comes back down the next!
