hey everyone! my name's Jerry and i have grilled out quite a lot, but this will be my first time smoking. i recently got a new grill, the char-griller duo 5050 with the side firebox for smoking. the gas side works flawlessly and i am hoping the other side does as well. got a picnic bone-in shoulder, had the skin on it, cut it off and tossed it, smelled like it had gone bad, hope the rest of it didn't. rubbed some mustard and salt&pepper on it and its sitting in the fridge waiting for tomorrow. its just under 7 pounds one question i do have, if its ok to ask here, is that i will be gone for about 3 hours tomorrow. is it ok to leave it by itself for that long? other than the obvious "shouldn't leave a fire burning unattended"
