If the Greenland ice sheet melting away, Arctic sea ice at all time low amounts, and 95 degree temps. in Alaska for a stretch of time don't convince you - nothing will. These are all verifiable by recorded data & aerial pix. If I see bear tracks in the snow and someone tells me there aren't any bear tracks there in the snow ………………. I'll go with the tracks.
We get nowhere near the cold of Minn. & Wisc., but I can say that crabs are just less hassle & are tougher than "regular" apples. Diseases don't seem to affect them as much either, at least here.
