My grandpa had a 1940's Willys jeep that he kept at the lake house to move the boat and pontoon in and out of the lake. He had taught me many times how to start it up (which had a specific way) and finally taught me how to drive it when I turned 12 y/o. At 13 he was letting me back the boat and the pontoon down the ramp and pulling them out along with driving it around the gravel roads in the area. Good times!
