Did two slabs rubbed over night with wild willy's number one-derful rub. I had cut each slab in half to fit on racks. Smoked with apple for 3.5 hours (had to go longer as it took a bit to recover temp). Foiled each rack with 2/3 cups apple juice for two hours. Covered with some Stubb's BBQ Sauce for 45 minutes. So tender and fall off the bone they were amazing.
