What's the difference between a grill and a smoker? How will the food's taste and texture differ when I smoke it? how about if I grill it? I'm a long time lurker of this forum and I've read that Weber is a pretty good brand and I want to buy a grill for my barbecues (please check the link). I'm having some second thoughts though because I'm pretty much considering a smoker. which is which? a little help anyone? thanks!
