Spring in Ohio is hard to beat, especially mid-late Spring when the temperature is high enough that you can comfortably wear shorts outside, but not so hot that you need to run the air conditioner...
As I grow older, I find that I hate the cold more and more, maybe I should move south...
autumn, mostly cuz i live in the south, and i love fishing and hunting. plus it's cold enough to feel WAY good outside but not too cold to the point where i have to where pants. ewwwww pants.
