First post here! I want to smoke a 2 lb. half rack of baby back ribs on my gas grill. I smoked some chicken using some hickory chips in the corner of my grill, recently with great results. But, after looking around at various places on the net, there are a couple things I'm unsure about. Most places say the cook time 4-6 hours, at around 230° but would this apply to the smaller amount of meat that I have? Also, some places say to include a tray of water on the other side of the grill to keep the ribs from drying out. But, given the "wetter" heat of gas is this still necessary or not or is it still a good idea to do it?
