I've been using an electric smoker (Smokin' It 2 -- highly recommend) for about 5 years in rain, shine, snow, cold, whatever mother nature would throw at me. Just bought a Louisiana pellet smoker and knowing (I think) how sensitive the pellets are to moisture, can you/do you smoke in the rain? I'm guessing you need to keep the hopper covered while you're filling it but other than that, any thing else you need to think about?
