Yes I agree, March is really still a winter month, we seen to be open to near 6 months of winter weather now in this country. However with noticably lighter days, sun you can actually feel the warmth of and the general 'fed upness' that people have of winter by this time you can't blame people for wanting spring to arrive.
March can be cruel (Easter 2008) or kind (last year) depending on which way you look at it!
