I have killed birds in the rain. I had one of the craziest days with an approaching thunder storm and will never forget it. My son and I were in NY and every time the thunder went off we had gobbles coming from all directions. Called one in and shot it, while we were taking pics 2 more birds came in and ran right at us. Could have easily shot another but we just sat and watched the show. Most amazing day ever in 32 years. My son and each got a bird and watched 3 more rush in 15 minutes. After the rain hit it shut down. I will never miss a good thunder hunt if I can help it. No one likes the rain but birds are still out there rain or shine and they Still play the game.
