AOPA Netherlands organised a fly-in to the ex-air force base at Twente EHTW on 8 July 2017. I took the chance to fly there on the way to Annemasse. Quite a few aircraft flew in - probably 100 or more.

Later on there were lots of thunderstorms across Germany and Switzerland which were easy enough to avoid using the ADL120 and the Mark 1 Eyeball.
