Spring is here. The Spring equinox was yesterday, with days being longer than nights from today till end of September. A perfect time to visit the Kola Peninsula. Lots of light, the roads are mostly clear, bitter colds are gone yet lots of snow for skiing and snowmobiling, and there is still a good chance of seeing Aurora Borealis. Last night it could be observed right in Kandalaksha, despite lot of local light pollution.
