Thanks Dave,
Now we don't feel so left out.
Everyone might want to notice that the temps are in centigrade, not
Fahrenheit
It is still off for this area, by a bunch on the cold side but i guess we
just need to let common sense work and account of that.
Last year the low was -39 in Watertown and colder in other areas that no one
wants to put a weather station in....
Tell me again why i live here?
Later,
Bob
