Was planning to buy chuck roasts but when at the store I found arm roast for the same price. They look to have good marbeling without all the junk that sometimes is part of chuck. Anyway... I now have four 3.5 pounders on the chargriller. Two for me and two for my brother. Smoke to about 160 then foiled and into the oven so that I can sleep for a few hours. Good eatin tomorrow, eh!
