A Finnish Contribution
Sakari Pönniö's Finnish Insulator Photos
This superb shot was sent to me by Sakari Pönniö from Finland. He states that in the 1960s this was a common site but is now rare. This image was snapped in April 2007.
And he continues... some more images taken 7.6.07 at Savonlinna in Eastern Finland. This also is nowadays history here.
