Looking back, I think I had been scared to try smoking a brisket. Having never seen chunks of meat that size back home, it's a scary commitment for two reasons. One, you can't eat a brisket by yourself. That means you have to invite people round for brisket. This has to be done in advance, and that means the promise of edible brisket. What you've done there is set yourself up for a fall when, actually, the brisket turns out to be terrible. Your guests will go hungry, probably destroy your property in a fit of rage, and eat anything they can find, even that expensive cheese you were keeping for an occasion more special than your house being ransacked by former friends.
Two, it takes so long to do it right that you need to block off two days of your time. In this busy merry-go-round world we all live in, where demands on our time are everywhere and anywhere, who can actually spend sixteen hours or so doing one thing? Unless that thing is video games, obviously. No one's relying on you to complete Fallout 3, though.
