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?
