Mike,
I don't read the Rider Down much, maybe I should scan a bit more often.
I'm very sorry to read about your dad passing. We all know he's doing better now. Sorry for your loss.
My dad made to 11 days prior to his 95th BD. My mom had passed about 15 years prior to him. In his later life, he got into the local history of the community and had MANY stories to tell about his youth in the area. He was sharing these stories with the local area museum curator. He told me once that he was having problems finding older people to pick their brains about the area. I told that he WAS THE OLDER PEOPLE... The area was rich with logging back in the teens, 20's and 30's.
He was a biker by choice, or by necessity I guess. Back then he rode whatever he could because he didn't have a car. And Michigan winters were always eventful. He had family in WV and he would ride from the Mid-MI area down to WV. He told us about one time he was riding back through Indy and stopped by the race track. Back then it was all brick and they were doing repairs and it was a lot looser in security back then. He asked if he could take a lap and they say hey, go for it. My brother and I did some checking and around the time dad said he was there, they were doing work and people taking laps now and again was not that uncommon. So all the men in my family now have taken laps on the I-500 track...
Mike, I lived so close to my dad in later life, but did not take the time to spend with him as I should have. I miss that now, but I have great memories...

I'm sure you will carry your memories until you meet with him again.
Ride safe my friend and see you next year in ES.
