While not living there, I have traveled there quite a bit. Been to most of the places you mention. I believe the only two I've missed are Copper Peak Ski Jump, and Fayette Park.
I have given serious thought to moving back up ? I just doubt the winters & my arthritis would mix well... I have been looking in the Traverse City area , thinking it might be [a-tad] warmer..... If at all affordable ? I'd like to be near / on the water. Yeah I know high priced neighborhood
