Where abouts in Fla.? I was born in Tallahassee, went to school in Venice, and have family in Pembrooke Pines and Davie.
Tip on smokin in the cold, especially using anything other than a woodburner (which I assume you are being as you're doing an overnight).
Go light on the woodsmoke for the overnight. If your temp drops much below 225*, you'll get alot more creosote plate on your meat than what you want. Put the woodsmoke to it before you go to bed, and add more in the A.M. if you want.
Good luck, and Good Butt Handlin',
Tim
