I only stayed at Port Crescent for 1 night, then at my sister's place in Deckerville for a night, before returning to MIL's place.
The next week I again went camping for 2 nights. I intended to stay at Rifle River Rec Area, but there were no nice lake views and the mosquitos were horribly thick there. So I decided to head up to the Au Sable River and check out the Huron NF campsites there. I was pleasantly surprised.
The CG check-in is at the Lumberman's Monument:
I asked about campsites with water views, and they suggested one on the north side of the river (about 5 miles west, a mile north, and 6-7 miles back east). The rustic campsites are in the woods along a sandy two-track. Mine was about a half mile in.
I set the camera on the car's side mirror (forgot to pack the tripod) and took this 'selfie'.
Notice the sandy bank just over my left shoulder? Walk up that bank, and this was my water view:
During my 2 night stay, I was the only camper in this entire section. I saw 1 young guy on a dirt bike go by, as well as 2 rangers in a pickup. Oh, and 2 boats went by on the river. That was all! What a quiet, private spot. Hardly any mosquitos during the day, either. The fee for 2 nights totaled $23.
