Snow Joke

Just a shorty.
Rural Powys - despite limited need re snow would it not be sensible to have 4x4 ambulances available?
after all, 2WD not too hot on mud, snow,deep water - all year 'round
4WD good at aforementioned and still usable when the weather is fine.
Doesn't take much to work out - does it?... does it? ;0)
