Last year I lost my cap on a small road in Danmark. From the corners of the eye saw it flying in a fraction of a second.
200 meter later I could stop and park the 4/4.
I walked back on a muddy field with high gras next to the road and searched for the cap. Without success.
So I walked back to the car - again searching on the muddy field. No result.
As I arrived at the car

left the 4/4, walked around the car AND TOOK MY CAP FROM THE LUGGAGE RACK......

Than I had a look at my shoes: Cap saved but the shoes had to go in the bin.

Next part I bought for the 4/4 was a cap lanyard
