I have been for the Saturday ride a couple times, but wont be going this year. Lots of old bikes, all running. I got goosebumps at the start when all were fired up and awaiting the roll-out. I have been to the Sunday show one time, but didn't show my bike: its a rider not a showhorse. If you look in the events page or the calendar, you might find photos from earlier Gilmore meets, I think they are still there. It is a terrific place and well worth a visit.
I try to post Stockbridge dates if I know them, also Holly.
Royal Oak and Ypsilanti have weekly bike nights.
Plymouth had (past tense) a fall Sunday bike show.
