As the Northeast prepares for yet another Arctic airmass, here in Tucson the bougainvilleas are doing fine. Most years in late February this exposed corner would be a convolution of bare wood, badly needing pruning. Of the 22 (non-contiguous) years I've now lived in Tucson, this winter was among the top two or three warmest. It's no coincidence that the ranking would be approximately reversed for the same 22 winters in Pittsburgh.
