Winter is here, at least for those of us in the northern hemisphere, and with it comes a whole bunch of seasonal changes. The leaves are gone and the trees are naked, the grass is hidden beneath the snow, and the ducks in the ponds are ice-skating instead of swimming. The landscape is barely recognisable when compared to the summer months, and as you can see from these pictures, many places look incredibly different when juxtaposed against pictures of the opposite season.
