Pardon the obvious pun, but these are cool!. In related news, it went up to SIXTY EIGHT degrees in Baltimore today!! Aside from some large, grey/black mounds of plowed snow in area parking lots - it's ALL gone. In one day. Amazing! As with most March weather, it is about to change, and not for the better.... By the weekend (Steve) - they are predicting snow showers, so plan on bringing the London weather with you this weekend when you visit.
UPDATE: And in other news that spring is well overdue, a man in Fairbanks Alaska, who left his sprinkler on in October, now has an 80,000 ton, 150 foot high ice scultpture in his backyard. Look closely at the picture for scale. The guy that built it is standing next to it and is 6'9" tall and weighs 350 lbs.
If you can ignore his deranged anti-global-warming rant (which I would strongly advise doing) this is really cool...
