Mine was back in the early 60's when a new highway was put in across our property. Four lanes, a center turn lane and emergency parking on each side. Plus, no cross streets or entrances for 3/4 miles. Our tree house was on a small hill over-looking the highway, and the area soon became the "local" drag strip. The only problem was that the racers sometimes lined up too far down the road. So, to help them out, my brother and I would grab some white paint and a roller and put a starting line in just below the tree house. As soon as we heard loud cars, we were out of the house and up the hill to watch the races. Damn, that was fun!! Occasionally, the state would come out and sandblast our starting line, at which point, we would roll out another one, ready for the next nights races. I remember one afternoon watching a supervisor telling his crew to get the damn stripe off the road. They did, and we put it back. We even "liberated" a 5 gallon bucket of ground glass to spread on our new starting line. It looked good!! The next day, the highway crew was back, and the supervisor was yelling at his guys to clean up the damn stripe. They cleaned it and as soon as it was dark, we replaced it. I guess we won, because the stripe stayed there until it wore away. I watched Corvettes, GTOs, 442s, even a new '66 Toronado line up against a '55 Chevy with a 283 and a 4-speed. The Chevy won, but it was cool to watch. We didn't play video games or talk on the phone. We just kept the "track" open behind the house. No one ever had an accident that I know of. This was on HWY 199 heading west out of Grants Pass, Oregon.
