Thanks Joe.
I did six racks yesterday and expiremented with different rubs, in foil and no foil, etc. Amazingly, I think I made six terrific racks. I gave two racks to my neighbors, kinda my way of saying "sorry you have to smell this every weekend". I had them rested for an hour and brought to them in a towel. I don't know what they expected, but the one neighbor came running over to say how good they were, while his wife called my wife with the same type of comments. Even their teen daughter was heard yelling "oh my gosh!"
My big tip with Costco ribs is to NOT buy racks that are too big/heavy/meaty. I am buying the smaller packs I can find, usually about 7 pounds for the three pack. Costco has most of there packs at 8-9 pounds - lots of meat. But you tend to get two huge racks and one smaller in the middle, so you are managing too many different variables.
Pictures next time. I am still learning the forum.
