Like similar oaths (jimminy crickets etc), jeezum crow is a thinly veiled blasphemy. Highly regional, almost confined to New England, and according to the Dictionary of Regional English (DARE) it likely sprung from Vermont and upstate New York vernacular speech.
Tropical Storm Irene "fatigue" may have subdued coverage in the general media, but there are still needs to be met in Vermont. Ms. Mitchell of N'Eaststyle and I dreamed up this sticker a few months back for its woodsy-vibe (honestly as just a truck/skate/snowboard decal) but have re-purposed it to support the ongoing efforts of the Vermont Food Bank who have been stretched, and tested following Irene.
