If its not raining too hard, I will usually stick it out. If its a flat downpour, then I might come out. Depends on the time of season. If its early, I will usually come out, but if it's November, I'm staying hell or high water. That is unless it thunders.

When hunting in the rain, I always let my bow air out. I like to take an air compressor and dry it off. Pay special attention to all the little nooks and crannies too.
