Frozen world

Our lakes has been frozen suddenly even there has not been that much frost yet (max -10 C). Today only -5 C. Even large open waters have frozen and that is very unusual on this kind of weather we have had so far. I really hope we will get more frost for couple of weeks to get that crystal clear and smooth ice much stronger. Then we would have excellent conditions for natural ice skating. Some brave ones seemed already been skating near the shores, where the ice thickness was about 3 cm's, which actually is enough for skating. I also walked and laying on it for photos (check the extra) and it didn't got broken under my 80 kg's :)
