We have a large number of ticks where the camp that I work at is located. We talk about ticks during the health part of camper orientation, and we do nightly tick checks - the campers get a tick check buddy to help them check their scalp and such.

We have more problems with staff than campers, because the part of the season where ticks are really heavy tends to be during precamp, and they are more cleared out by the time that campers get to camp. We probably have about one staff Lyme case every other year, generally caught early. I've had it. I don't recommend it.
