You can request from quite a few airports / aerodromes QDMs.
Last time I asked for a QDM was to demonstrate this to a passenger as one of the available navigation options.
I then didn't actually fly the QDM, as I wasn't actually intending to return to the airfield just yet. They called me up a few minutes later, unasked, with a revised QDM - I suspect they saw on the radar that I wasn't following the QDM they'd given me and thought I was actually lost.
