The message
from SusieThompson contains these words:

We are thinking about buying a 10x10 polytunnel for our new garden -

The other option is, of course, a greenhouse,(snip)

Both could be exposed to some of the gales that can blow in the valley
where we live. Here on the Isle of Arran we don't get too much snow and
the winter temperatures on the whole are fairly kind.

We almost got stuck in drifted snow on your road last winter; we got
taken by surprise because there wasn't any at all over on our side or
down on the W coast.GH roofs are better able to cope with the weight of
snow, I think.

Although there are polytunnels elsewhere on the island, I've not
noticed any in your neck of the woods. It might be a good idea to ask
locals if polytunnels can survive there.

Janet.
