This is a great fundraiser to run in October. Discover all of the haunted places in your area and research their history. Advertise that your group is offering a haunted tour bus ride. Rent a bus for the day and gain permission from each place you want to stop at. Check with your local municipality for commercial drivers license restrictions. Find a local historian or paranormal researcher to act as your tour guide. Make sure you have a PA system on the bus or portable speaker so that everyone can hear the tour guide. Decide in advance how long you are going to stay in each spot so that you stay on schedule. Stop at a restaurant for lunch. Decide if you want to include lunch in the price of the tour or have each person pay their own way. Pre-arrange with the restaurant to have tables reserved. Ask them to create a “spooky” menu to fit with your theme. Create a souvenir map with a small blurb about each stop for the participants to take home.
