Jeff when i was a very young man I was hired by a Harley shop.
Why?
Cause I had bought a wrecked Harley from them and made it work again. (very wrecked)
The owner decided I might be an asset?
His name was Fred and he owned several shops in Puget sound.
I just looked him up and he has passed.
Maybe my point, ? I think,?
I have been in the thick of Harley crap for the long time.
Albeit I did not last long at the harley place as it bored the crap out of me and other stuff.
