Wifie and I spent a nice day at this clothing optional place on Wednesday, 8/18:
https://northavenresort.com, located in southeast MI near the MI speedway! It's very nice, glad we went, enjoyed hanging out by and in the pool Nudity optional everywhere in the resort,, including the pool! No one there almost. Better than average facilities for a nude place, IMHO. The owner Monica took us on a thorough tour on a golf cart. Besides a sizeable pool (88F!) with a zillion lounge chairs it offers really nice RV sites and rigs, some seasonal and some transient. Not AANR but no bother at all to us about the adult aspect, it being a Wed. Imagine the weekends are rowdy. Will not be our last visit. Day fee was $40.
