Just thought I'd dig up this old thread, and add a new story. Two weeks ago, my wife and I spent several days in the Traverse City, MI area. Of course my wife likes walking and shopping the downtown areas - and I did as much of that as my feet would allow. But we spent a lot of time driving, sight seeing, dining, and wine tasting at the huge number of wineries in the area.
But the best part for me was Sleeping Bear Dunes (A National Park area made up of large sand dunes on the eastern shore of Lake Michigan.) They have a "dune climb" area, and I decided to make the climb. It was a warm day and it's a bigger challenge than it appears from the bottom. Halfway up I wasn't sure I could make it. But I took my time and eventually made it to the top, where the reward was a park bench at the top of the dune, with a great view and a cool breeze coming in off the lake. Fortunately, going back down was much easier for me.
I did pay for it a bit the next day, but I think it's good for everyone to push their limits once in a while - no matter what your personal limits are. Keep posting your stories - I love to hear them
