Hi Larry I have been the one who has organized the thumb run event for the last few years. For a few years now it has been harder to get into Port crescent camp ground do to over crowding. And the last couple years I moved the get together to Sleeper S.P. which is on the same road but just closer to Caseville. And has been less crowded. So I would like to recommend the Sleeper S.P. is our meeting place this year too.
There really isn’t a organized ride to and from on Sat. And we typically have a ad hoc ride on Saturday too. And last year we eat at the site on Saturday night due to the Covid issue. And we have typically make to decision for dinner on Sat night. There are plenty of option in Caseville and Port Austin.
I hope this helps clarify this event
