Also, identify around half a dozen potential theaters in the local area. After hashing around logistics for a couple of days, a final decision on the priority of theaters should be made approx. It helps to have tall stuff at the display table, particularly a freestanding panel display at one end of the table that will project above crowds. Movie related stuff helps. A prize drawing also can help to draw people in.
Participants merely have to fill in a small card with name, address, phone number, and email.
Continue down the priority list until the proper number of theaters have agreed to allow a MS presentation table. Although a theater display will probably not merit mention or coverage for most of the local press, chances are you will get posted on a couple of the community events calendars, and possibly may get a press crew covering part of the event. Everyone involved should have their responsibilities clearly laid out. Who is responsible for table set up, who is working the table at all times, who is responsible for clean up, etc. The table and displays should be set up, and the folks working the table should get the crowd interested.
