Adam, Yes, it will be cold, but we love to ski. Plus as you know the USDA Zone is a average minimum cold thing. Actually the areas I will be moving to will get as warm(hot) as here, zone 5b/6a but.... for a shorter length of time. Also, my new growing season will be shorter for sure. But compromise is the thing to do!
Wintercare is actually the same, the trees that will be able to take only 25-35 F temperatures for the winter are being protected here already. My present temperatures unprotected outside are in the single digits most winters, sometimes below zero and always long stretches (several days to a week) of low teens.
Scarves and ear muffs...... ear muffs..... we don't need no stinking ear muffs
