did you put a rub on them?
Try taking a 1/4 Cup of your rub and add it to 1 Gallon of water with 1/2 Cup Salt and 1/4 Cup Sugar ( 1Tbs Cure #1 optional for a Hammy flavor ) and make a Brine. Soak them Buzzard Boobs for 24 hours, dry them off apply rub and get your Smoke on. You will be amazed at the juicy tender flavor you will get...JJ
