Guru tip for cooking in bad weather.
Just got off the phone w/Shot Gun Fred. Thought this might be worth mentioning.
It's not a good idea to use the Guru in the rain. But it's also not a difficult problem to correct.
Take a clear plastic sandwich bag, punch it through the back of the unit then place the unit back into the vent cylinder.
That way you can still adjust the controls if necessary and the unit will stay dry.
Out of all the bulletin boards in all of the world you had to walk into this one. Didn't ya.
