I was just wondering what different types of props or walls could be used to direct traffic through an outside haunt (aside from trees). My Haunt is going to be in a Rodeo Stadium and part of it will be outside the physical structure I'm building. If I put up a little dinky fence, then people will be able to see it all from the queue line before they even go through it. Is there anything tall that would work? Maybe corn shucks? I'm really not sure. Any help would be great! Thanx!
