I cooked exclusively on charcoal previously and while I loved that and the process of doing it while single, being a family man these days I don't have the luxury of being able to grab a 12 pack and babysit a grill for 8 hours without "adulting" things geting in the way these days.
Don't tell my wife this. Sometimes a guy needs an excuse to be in the backyard for a bunch of hours crushing beers.
