There was no sun almost, and it was too warm so still droves of cyclists about that forced us to drive slow..

This is to get an idea of the 'Dutch Highlands' ... This is a joke [ highest point +85m]. Official name " Veluwe"...

 

I remember the Nits had a song called 'In The Dutch Mountains'...and now I know what they look like

 

I didn't know the song. Just watched the video. I think they refer to rooftops..

But in the days of psychedelic music, lyrics didn't actually needed to mean anything..
