You only learn how to make good BBQ by making bad BBQ. Probably needed to be cooked another hour or so until the probe or fork goes in and it feels like melted butter. 203F is another suggested temp but temps are just guidelines. Its done when its done. Also you really need to rest the meat for at least an hour after pulling. Can't stress this enough.
Thanks for all your tips. Even though it didn't turn out as well as I would have liked it was fun doing it even though it's an all day commitment.
