Sherry, I don't know if you followed Mark's musings here about his adventures but he certainly was always very complimentary about you. He shared a lot pics of you and his mom from BBQing in the back yard to Cars and Coffee outings with one or more of the cars.
He had an interesting life. I met him just once when buying some parts from him and that was like in 2004. Here is the post:

He doesn't mention the parts because they were insignificant in the context of things. A pair of megaphone exhausts that ended up welded to a Ben muffler for the Ragamuffin.
