RE: I'm thinking rain
I don't mind hunting in a light to steady rain either (God bless Gore-tex). Especially if it starts after I'm already out and about. There's just something about getting out of the truck when it's already raining, especially if it's cold.
I know a lot of people that won't go out if it's really windy either, but about 10 years ago, I called a big gobbler in off the roost while the wind sounded like a freight train coming down the side of the mountain. I have no idea how he was even able to stay in the tree!
All that just to say, if you catch the birds fired up, it doesn't always seem to matter what going on weather-wise.
