No salt flats in Netherlands??
actually - it is unique -not like concrete as it is deep
some years it is absolutely FLAT for miles n miles
that is why speed runs are done here --- 200 mph feels like cruising along at 60-- your only referrence is the black line to keep you going to/thru the traps the reflection is also unique - a light meter reads same - up or down
If you ever want a full even tan (burn) this IS the place. the purple line on map ,is 100 miles long--almost halfway, is our flying field
