Jim, I went a few times after the change over to jets, but those darned piston engines got soooo expensive, and hard to find parts for, I remember as a kid, if Mom and Dad could have bought me anything I wanted, it would have been any one of those 12cylinder monster, the were going for $200.00 in them little magazines, talk about hard to come by, 200 bucks in those days would feed us for a long time. The roose was about the same, but the "thunder" was gone.
