suggestion for "garbage" –
I hope professional haunters won't hate me for making this suggestion.
In a few haunts I have seen, there is a lot of garbage that could be used or useful to home haunters. If you professionals could make a pile or container of garbage (broken 2x4s, torn masks, busted fogger, clipped extension cords, etc.), that's gold to home haunters.
Hell, if you have after the season mess, ask a home haunter and they will remove "garbage" for free.
*Don't think of home haunters as future competitors. Most of them just want to scare the kids on Halloween.
