Just talking to Comfortably (the Numb Branch if the family), about what happens to growing things in certain locations, I thought I'd add my two[pennorth...
Years ago, when we originally had 'Plot G', there was an elderly couple who tended their plot to perfection, just up from ours. They were always there, doing this and that, (he wore a tie, like Percy Thrower did) and of course, we all got talking one day.
He said that they'd chosen to retire to this village, because records showed that rainfall was way below average for the area, and that a generally dry time could be had by all.
We wondered about that, but have never actually proved him right or wrong, (well why should we, he and his wife were delightful people), but it's always got me thinking about researching the immediate (i.e. say a square mile), of a location, to see if the terrain layout really does mean that rain either goes round the area, or just doesn't work here very well.
Comforts lives not that far from the sea, so, with my limited knowledge of geography, I'd expect the air to be salty, damp, nice and sunny (south coast remember), and as it's a flat part of the region, a rather pleasant and positive location to grow things in, with such a big sky to stare at as well.
We certainly mss a lot of the rain here, and being on a hill, we don't get floods or pestilence (including frogs), but it's an interesting subject to consider, if one wants to grow stuff in places like Cornwall, which is near Spain, or places elsehwhere, which aren't...
