My most valuable lesson was don't forget to punch a hole in the aluminum foil.
1. Full Packer Brisket in about 9:30 PM
2. Temp @ 225
3. Watch News and go to bed, thinking I have done brisket no need to go check on the smoker.
4. Wake up with the wife screaming "What the *&^( did you do to my patio."
This was not priceless! I am sure if the product was not so darn good both of us would have been gone. Bob
