I saw one about 12 years ago.. and talked to the guy.. but not much.
We (about 6 guys) were out on a lake at night in Oakland County on snowmobiles and pulled up at the boat dock in front of a big fancy house to crack open some beers and BS for a while.
A few minutes later we hear this burbling droning noise and look up to see a jiggling headlight approaching thru the snowflakes.. and up rides this guy on one of those Chrysler Sno-Runners.. Wow!.. No kidding.. none of us had actually seen one before.
He says... Hi.. Do you guys know Laimbeer?..
We say.. No.. Why?
He.... This is Bill Laimbeer's house. (pro basketball player)
We... Oh.. Didn't know that.. That is one of those Chrysler Sno- Runners.. isn't it?
We.... How good does that thing work ?
He.... Oh.. It's alright.. It's not very fast.. and it won't go thru very deep snow very well.. it doesn't have enough power.. it's much better on packed snow trails.
We offered him a beer and he declined .. and off he rode into the dark.
The whole process of riding looked a bit unstable and wiggly.. but that could have been the conditions that night.
The motor was a 2 stroke manufactured by Chrysler.. they (Chrys) made mini-bikes with that same motor way back in the seventies.. and made outboard boat motors also... I think they might still be making them (outboards).. but now they are called "Force".
That's all I know about them..
