I am upping the difficulty on some in this due to the DNFs. I had gone back and checked one that was in question and it was there, I probably will head there this week after work to check a couple, to make sure they hadn't gotten muggled.
With today being a holiday, my youngest daughter and I went to perform maintance on a couple caches, all is good with them. We then hid 12 more tied to the river. I thought I saw someone in a yellow Jeep going for my caches down on the river, but there were not any logs, so I guess they were not.
I really enjoy this area, sort of out of the way, I have not seen many people around the area. Perfect to avoid muggles.
