Hello, I am just getting started with smoking, I have a friend that does a lot of smoking and I love that rich smokey flaver. I stumbled on to this site looking for some ideas on building a smoker. I am not sure about the size however, I tend to go way over board whith my plans, been thinking about using some old water tanks that are laying around about 100 gallons. does this seem to big to you guys. thanks for the input.
