Israel is a small country without many wild open spaces that are far from inhabitants. In order to reach clear spaces for wildlife photography which are cleared from population, one usually has to walk at least two days on foot.
Because of the heavy photography gear, I have found myself more than once carrying 30-40 kilos of gear on my back. This has made the shooting days very hard work. Even though, I don't have any problem with it: this is how I combine my two greatest passions, for photography and for hiking.
