Friedrichshafen is full of Zeppelin things. Like this climbing structure. None of us had imbibed enough good German beer to pretend to fly it for a more amusing photo but I think both of the bystanders were wishing that they were seven years old and could climb in. I think we'll need to have some things like this at our passenger facilities, sized for both adults and children*.
* there is a Zeppelin simulator at the Zeppelin Museum that is run on an occasional basis when a pilot is available. Cool.
