Thank you Dutch (and Bear) - yes, she gave me the nod and said they were very, very close. My only complaint was that the underside had gotten a bit too charred because I haven't modified my smoker yet. So whenever flareups happened or the temp got too hot on the right side, it was burning the ribs underneath. We'll get that part fixed.
I did use the "dry rub" recipe that you can buy from this website, so I cheated a little bit. I'd leave out much of the cayenne pepper myself, but otherwise, the slab was devoured in under 2 minutes! Very tender...the best ribs I'd ever made.
I also did a pork shoulder using the webmaster's "cook to 208 degrees" method - and WOW. That made for some great sandwiches - again, I only got two and everyone else had pretty much powered it down before I could come home from work the next day!
