Running an outdoor maze, and even more so with corn or forest, can have ALOT of problems.
1- Since it is outdoors and is exposed to the elements, weather WILL decide if your attraction opens or not. This is were having a indoor
attraction comes in really handy.
2- In our maze we have NO electricity... Electric company said it would cost well over $2K to run it... so screw it. We set-up around 3 high-powered (8000 Watt Troy-Bilt from Lowes) in locations were we want power and run cabling. We really promote the idea of darkness and being "alone" in the woods... so we create 3 major "scarzones" in our maze. One in the beginning, one in the middle, one at the end. We useally will give each zone a theme... and decorate it to the MAX! This allows us to have a "themed/created" attraction and a natural/dark setting with the trees.
3- As far as codes go... since it's outdoors and open aired no sprinkler system is needed. However, we do set one up by running "lawn sprinklers" through the maze (several hundred) and all we have to do if pull the spout and away the water goes!
HINT: This could work for an indoor attraction needing a sprinkler system... just invert the lawn sprinklers to face the ground and hook-up!
But we always post that there is NO smoking in the haunt at all times. It's outdoors, trees ARE flammable. But we also keep a cop on hand with the fire dept. on speed dial just in case something wierd happens.
4- When working with electricity outdoors... moisture/dew WILL be an issue. DO NOT turn on ANY electronics in the morning... Just don't do it. Let EVERYTHING sun dry (mainly generator cabling)... But I really suggest taking down and setting up ALL electric componets up and down EVERY night... Also, as the night goes on, dew WILL collect on the cabling and lighting/fx instruments... So do several scheduled "checks" a night... Maybe after every 6-10 groups!
5- I don't know about the insurance as I am not the one that deals with it.. sorry.
6- Air.... Hmmmm... we ran one SMALL compessor (actor operated... shooting with)... and we just placed "away" with the generator.
7- You soon learn that having a small "control area" in the haunt (as with any) will be very helpful. Have the electric/air power systems in one location is possible... then when something happens you only have to go to ONE area to fix it... Also, try to keep all cabling off the ground. Since we run through trees... all of our cabling follows the tree paths... and NOT the customers paths. But if a cable MUST cross a customers path... place a little dirt and straw over it and SMASH it into the ground until it is flush and NO ONE will trip over it.
Our maze is made of evergreen trees planted to form the paths/rooms of the maze. It takes up 18+ acres on two hillsides and takes around 1 1/2 - 3 hours to get out.
I hope I was able to help... if you have ANY more questions please PM me. Happy Haunting. -Tyler
