It is not my pictures but a friend's. I haven't seen him for 40+ years till he suddenly sent me an email with this link:

I grew up in Oslo; Norway, and all the pictures are taken not far from the city - a lot of them are in fact inside the city border! So here is where I spent several weeekends outside (in something we call a "huk") or in various cabins, many built by teenagers like myself at that time.
Enjoy ;) (I did when looking at them remembering long forgotten places and people.)
