Yep.  It was 32 on the front porch this morning.  Took a quick walk through 
the orchard while the coffee was brewing.  Probably was even colder out 
there.  Everything was frozen - leaves, new shoots, you name it - I even 
snapped off an 'asparagusicle' to munch on the way back to the house.
Bet I'll have some black, wilted foliage when I get home this evening, and 
it may have doomed the majority of the fruit for this season.
Temps are supposed to be back up into the 80's again within a couple of days.
