A couple of weeks ago we were visiting Michigan’s Thumb area. One afternoon, 54 weeks after we began letterboxing, we visited the Sanilac Petroglyphs. Unfortunately the petroglyph area was not open. I think the kids would have enjoyed seeing the carvings up close.
Fortunately, the hiking trails were open and the letterbox we were seeking was placed along the trails. The trails were pretty muddy. One of the bridges we crossed dipped into the river below as we crossed but luckily our feet didn’t get too wet.
The letterbox was well-hidden and in good condition. It had a nice hand-carved stamp. This was our 100th find! Woohoo!
