I went to my aunt's house today and I seen a pic of a very old airboat. I asked her who was in the pic and she told me that it was my dad's dad. He past away the same year i was born. she told me that he was a wild life officer down in the glade for a long time. she said him and another guy build the frist airboats in the glades. I'm going to have here sent me a copy of the pic and I will post on here. The boat had no cage it just had a screen a between the engine and prop and one big rudder made from plywood
