Downpours and lightning are really the only things that keep me indoors.

I can deal with the wind, I just hunt from a groundblind and hope the wind calms.

I can deal with snow.
I can deal with a slight drizzle.
I can deal with heat.

It takes life threatening weather to usually keep me indoors. Even if the weather is crappy and I won't get a shot; a bad day in the stand always beats a good day at work.
