Sue far as something to go through I would suggest maybe a tree tunnel. I dont know if youve seen one. But the are like very cool and creepy. You could make them like silhouettes on plywood. you could stagger them left to right so you dont have to make so many. But 6 to 8 maybe 10 would look awesome as you leave your cemetary. You could have red eyes up in them or an owl or buzzard or maybe a raven. A hangmans noose. You could have them as tall as 8ft. Its just an idea. Hope you like it and can maybe use it. And it would be something cool for the customers to walk by or under.
