I colud have sworn, growin up that the prairie dogs hibernated in the cold of winter. but the other day it was 11 degrees, sun out 11 a.m. snow the day before, and they were out soakin up the sun. Boy did it turn the snow red when ya hit em with the .204. They stayed up and continued to look for a few spregs to eat. So much for hibernating. The dogs in denver.co. and the eastern plains are doin well. Coyotes, and the hawks sure love it when ya help em find a fresh pile. jc
