I don’t know about you but I find it easier to deal with hot temps.  Bitter cold weather causes me more problems than hot weather.  It doesn't matter if it's dealing with animals or machinery, the warmer weather is just easier on everything.  Plus your fingers work better when it's warm and traveling is safer too.  Rain does us more good than snow and it’s cheaper to cool a home than it is to heat one.  If I could choose below zero or above 90, I'll take my chances with 90.
