I took this picture a couple weeks ago in a different section of the Douglas State Forest. At the time I went on a rather long bike trek through the woods with a friend. We were out there riding the trails for about 4 hours and part of the trek involved carrying our bikes for a mile or so through brush when the trail we were on ended. Rather than turn back, we decided to push on through the undergrowth since we knew there was a trail further ahead.
The spot shown in this picture is a boardwalk that goes through a white cedar swamp. I think it might be some sort of bird sanctuary as there is a large wooden blind you can hang out in for watching for birds. There are also some numbered plaques along the path, but I didn't see any map or brochure that mentioned what the numbers represented.
