Yeah, I remember that Feb. 2007 storm and liked it as well. Admittedly, it was a bit disappointing because for some time it looked like a great widespread 12" or so snow event through the DC area. But even still, it was fun. I got ~3" sleet from that and maybe some glaze, and it did indeed turn into a block of ice for some time (it was very cold leading into that storm and then again after). I think areas just to the east of DC did get an appreciable ice storm from it.
I've said this before, but I also actually liked the winter of 2006-07, though many think it was "meh". We just missed the Feb. 2007 event being something huge, sure, and it was warm up through about the 3rd week or so of January. But dayum...February was a frozen tundra! I think we also got a decent mixed event later in January too, leading into that pattern. And Feb. 25 was like a 5-6" paste job. Feb. 2015 (and into early March) was remarkably similar in many ways with the frigid cold, but we maxed out our potential a lot better!
