Coming home on the two lane I run up to a Harley Davidson strolling along at 52 miles an hour. Between the hills we were going thru and oncoming traffic I couldn't get around him. Finally Over the next hill we came to I knew was a good passing zone, so I closed up behind him and just as we break the top of the hill I see him twist the throttle wide open. Well the oncoming traffic wasn't there so I twisted my throttle wide open. Poor guy must have thought one of his cylinders had died as the big 6 just blew him away. Probably won't try that again against another F6B. I certainly hate that, being an old truck driver and having had many four wheeler pull that stunt on my truck over the years when I was pulling out to pass a slower 4 wheeler.
