The experimental intervention is a performance-based educational program on Lyme disease prevention, and uses supplemental materials. An entertainment troupe delivers the intervention using comedy, theater, and vaudevillian techniques. The entertainers present three shows in different locations on the boat. Each show is about 10 minutes and covers the severity and likelihood of acquiring Lyme disease and the benefits of tick avoidance and search and removal behaviors. When people on experimental boats enroll in the study they receive the following free materials: a wallet-sized tick ID card, a laminated shower card with tick-removal instructions, a map showing tick habitats, a tick-feeling card, and an educational pamphlet. Control boats do not have performers. Participants on control boats receive education on road safety and injury prevention from rollerblade, bicycle, and skateboard accidents.
