We were at the Mulhouse car museum in July and were lucky to discover (purely by chance) that it was their annual Véhicules en Uniforms weekend. This meant that all sort of service vehicles - from buses to fire-engines to World War II military equipment - were on display, and their owners were giving free rides around the racetrack.
We rode in a variety of vehicles, but the most adventurous ride was in an authentic WWII era Willeys Jeep. Unfortunately I didn't take a photo of Susan wearing an American helmet of the era - apparently "bloody heavy".
We also learnt about the pompiers' bicycle - but more of that later.
