I'm an avid scuba diver. Ever the domain of the wealthy, scuba diving required both access to the ocean and a shite ton of money for travel & equipment. Not really having any of it, this awesome hobby just kinda passed me by.
Wooden Church in Kizhi, Russia. Kizhi Pogost, a century site on an island in Lake Onega in Russia. This picture is a pogost, a church. This building is still around after 400 years - and it's made out of wood!
