Yes, Dorset is quite pleasant most of the time, (they're in Poole, within walking distance of the park, dolphin centre and The Quay.)
However one year when I was down (early 2018) It snowed quite heavily. It's normally a 10 minute drive between the two sisters' houses, but 2 hours after leaving one sister's we were only about half way to the other sister's. We phoned the first sister to let her know how things were going and said we'd phone again in an hour. We dully phoned back in an hour to report that we had managed to move about 10 feet. By that time we had decided that it made more sense to return to the first sister's, BUT..... as we were on a duel caridgeway we wouldn't be able to turn back until we got to the roundabout at the end.
Another hour later we finally got to the roundabout which was blocked by a large lorry and all traffic in all directions was at a standstill. Eventually, with the aid of several other people, the lorry driver managed to move the lorry enough to unblock the roundabout and the traffic got slowly moving again. Once we were round the roundabout it only took about 4 minutes to get back to the first sister's house as there was hardly any traffic going in that direction,
