If you already have some portion of a haunt, this means you are serious and already might know more than they do. You can show pictures of rooms you have detailed even in your back yard or garage and say this is an example of what a room looks like. Compared to I have this dream and have scribbled out a 1000 thing "things to do list" and I want you, mister civil servant, to read it and be ready to talk about it, possibly even offer input like uncompensated engineering time and city planning or something that is just a dream.
As opposed to see this? This is how everyone in the industry does it. I have been to untold other haunts in other cities that are safe and successfull, this thing I built is just like them and now you can allow yourself to be excited as I am about having one in OUR town.
So, build the damn thing, take pictures of it, put it in storage.
If you were a band and showed up with no drums or guitars, no pa system and no definable talent and just a drawing saying you needed two 50 amp circuits someday would anyone care?
Another fabulous post from the U.S.Department of Wild Imaginings, now in spectaclar stereo, sponsored by the Adhesives and Sealants Council, suggesting ways to stick things together since the 1800s. Not fabulous in a gay way. Your results may vary. Illinois residents add 8% sales tax.
