I missed that you did this cook in 1.5 hours (until Bob pointed it out in his thread) Very impressive ribs in amazing time. Way back in the 80's we did ribs in about 1.5 hours, but that was boiling them first and then on the grill. Gonna give this a go real soon. Thanks Jim & Bob, excellent lesson in ribs...and after 90 minutes on the grill, a few minutes to rest, we were ready to eet!
