When I was young we did all our grilling on a simple round metal grill on tubular legs, with no cover. Things have come a long way since those days.
In fact, on another thread, BDL and I were talking about Bobby Flay, and the number of "barbecus" he uses on his BBQ Addiction show. Near as I can tell, he has at least 11:
1. A gas operated cooktop.
2. A monster gas grill
3. Two (at least) webbers.
4. A Char-Broiler type rectangular charcoal grill
