Well.....there's always next time. I've got one of those old bandera types (it was a less expensive one), and had a helluva time keeping the temp down. It was always getting up to 250+, and was hard to get back down to 225+. It had been 8 years, so I had forgotten a thing or two. I will definatley need to get one of those thermometers to drop down the chimney to keep a more accurate temp, it still has the original thermo which is probably off.
The meat was still ok, though, just not what I used to do.
I will try again next time we have some nice weather, and keep posting and reading to get more ideas!
