For most smaller haunts rain kills you. Especially if it rains out a whole weekend. If you're only open 10 nights and it rains 4 of them then you will more than likely be off 40%. Some of the people will still come, some will find other things to do (movies etc.), some that would have come 2 weekends in a row will only come once. A lot of people may see a sign or hear an ad or see the hearse and come on impulse....you won't get those people back. Even an indoor haunt is affected if it is a downpour. People here just don't get out and do anything in the rain and even if you are open in the rain people will think you will be closed and decide not to come. Snow even affected some this past season. However, all that being said....some of the bigger haunts don't miss out on that much business because people want to go so bad they are willing to get wet. We had a good season in the South last year with it only raining one night of our season, so we will keep our fingers crossed for good weather again!
