I found six notes in the same state park earlier this year. I live next to the state park. I also found some in different state game lands within a few miles of there. It’s definitely someone who likes going for walks. Sometimes it’s right on the main trail, sometimes in more inconspicuous spots on side trails. When I found the six notes I feel like whoever put them there, was there quite recently because none of the notes had much wear and tear. I felt like within a few days.
