I smoke in Loveland, CO at about 5,000 elevation. I use an ugly drum, 55 gallon home made smoker after using a weber kettle grill. I really like the ugly drum and have been using it for about 2 years. Only problem I've had with it was smoking a turkey at 8,000 feet. Was hard to get the temp high enough for long enough. I also am an avid home brewer and stumbled on to the site looking for info on PID temp controllers as I am putting together a electric brewing set up. Great info on the PID controller. Thanks!!
