RADIO CONTROLLED BOATS. The same thing could be applied here if you have a local park with a pond in it. You don't even have to sponsor an event just put a sign on one toy boat or have it tow a barge with your ad on it. You can have great fun with your kids with this as I'm sure they'll help you advertise this way anytime! Be sure to take a picture of the kid playing with the toy boat. You may get the picture in the local newspaper as a human interest story [the sign can't be too large or gaudy or the paper won't accept it].
