CC had a good point. The problem with SOME dripping from BBQ is that they're too smokey. For some reason those dripping really absorb the smoke and tend to be bitter. That's why sacrificing a disposable aluminum pan is a good idea. Let it char, burn, get crusty and dump the whole thing. Easy clean up. For ME, a grill shaped drip pan would be useful if it was made out of disposable aluminum. But noooooo, Dennis has to make them tough enough for the Army to wear them as helmets.
The good thing about the double drip pan is that the drippings wouldn't burn and it would be an easy clean up. As much as I cook on Bolo, I could have paid for the double drip pan with all the aluminum pans I've bought!
