Hello Mike, and welcome to the board! If its any consolation, due to a few die hards on this board, amateur 3 wheeler motocross and harescrambling is alive and well in Ohio!!! We usually have to run in quad classes, but at least we get chance to put on a good show! There are pictures posted all over this board and others for some of these events but viewing them may give you some flashbacks and reignite "the bug". Im just just finishing my seventh year of ATV MX and Harrescrambling, mostly on my TriZ, and even though I should retire, there's always "just one more season".
Again, welcome to the board.
