I got permission to check out an hour or so later, and quickly changed and ran into town to take a Dune Buggy ride over the dunes between Silver Lake and Lake Michigan. The concessioner leases the land annually from the state to conduct its tours, and with today being Father's Day, lots of families were out and waiting for a thrill ride.
This was like an organic roller coaster! We did have seat belts, and we needed them, as we leaned hard around the sharp turns in the tracks already laid down in the sand. Our driver drove fast up, up, and over one dune after another, and each time we stopped he shared details about the "sandwood" (like driftwood, dead, but unlike driftwood, the specimens are jagged, and lie in sharp, contorted shapes.
Here's a little sample of the fun! Well, having some technical difficulty uploading the video. Will keep trying.
