Well it's been on for 8 hours and the IT is 163, so I wrapped in foil and moved the probe to the large part of the flat as Bludawg and others suggested. Here is what it looked like before I foiled it.
I also stoked the fire to 300 to speed things a little bit. Anticipate it being ready between 7 & 8, we'll see...
Appreciate the kind words from the brethren!
