I did some a couple of years ago. Soaked them in salt water with some bbq rub (store bought) for a couple of hours. Then hit em with a little more rub and smoked for about 2.5 hours with charcoal\hickory wood. I thought they came out really good. Just me so I never get pumpkins to carve. Hoping my sisters family is doing jack o lanterns this year so I can get their pumpkin seeds again.
