Well, I'm glad to hear that I'm not the only fella that hunts the rain. My first deer was killed in a pretty heavy downpour. Since I've been hunting my lease, I've seen more deer on rainy days than dry days. (both heavy and light rain)
Since I'm just going into my second year of bowhuntin, I haven't gotten a chance to bowhunt the rain much. I just know I want QUIET rainwear.
Now, for the bloodtrailing issue,...............I'm colorblind!!!!!! So it doesn't matter what the weather is doing, I can barely see the stuff anyway! I have a VERY difficult time trailing game. I went help a buddy haul his deer out this past season, and he was pointing to this huge amount of blood spray all over these pines. I had to get within a foot or less from the blood to see it. It just doesn't stand out to me. I hope this does mean that I should stop hunting.
