At the top of Kolbensattel is an Alpine Coaster that you can ride down in the Summer.

Since it was only our second day in Germany and we were afraid every hike we took may include an Alpine coaster Natalie issued the proclamation "You can have one Alpine Coaster experience. Have it now and that's it!"

And a meme was born. To this day any time someone asks to do something fun the answer is "You can do it once and never again!"
