Unless it's lightning, I'm there.
Although I usually am in a tree for most bowhunting, I like being on the ground when it rains.
It's easier to still hunt when they can't hear you, and you may find very fresh tracks to follow.

Snow is the same way. One day I went out andthe ground was bare. It started snowing these really fluffy flakes, so I gave it an hour to accumulate and then started hiking. within a half an hour I'd found tracks of 2 deer traveling together. I spent the rest of the day on pins and needles running on adrenaline knowing I was less than an hour behind them. THey left the huntable area before I caught up, but that day still beats most others.
