Looks like you had a great trip 
after staying overnight at hank we travelled to hillegom for the ford museum, from the model t to about 1948, with over 200 vehicles,
then we wandered along the coast to den helder for the show we wanted to see in the first place, staged on the old naval docks (no mud or dust ), right in the town and everyone was very welcoming, we had a good time here ,
Fantastic pics there, look like good places to visit.
for really good photos of the weekend see
