Colonel - welcome, and God bless you for the work you do! As a former police officer myself, my thoughts are with my brothers and sisters in Ferguson! Time for this nonsense to end!
Congrats on the smoker! Under your time constraints, I would skip the pork butts until you have more time. Turkey breasts are short, and you can also smoke baby back ribs and whole pork loins in 4-6 hours. Check out the loin and rib recipes. Also, whole chickens only take 4-5 hours, and are incredible! If you smoke a pork butt, you can go to 175 internal temp for sliced butt - pretty tasty! Pulled pork takes much longer to get to 195.
Stay safe out there, and let us know how we can help! Glad to have a real American hero on board!
