Where to place thermometers when cooking a brisket

[hexidecimate]

Doing a brisket for the inlaws (outlaws?) this weekend. I have two thermometer probes to use. I'll use the first one to track the ambient grill temp, but am not sure where I should be sticking the second.

Thanks in advance!

One in the thickest part of the flat, one in the thick part of the point. Focus on the flat.

Brisket cook is going to take awhile. You don't say what you are cooking it on.
When using my Weber kettle or even the PBC I only worry about pit temps for the first few hours. I will most likely reposition this hunk o meat a couple of times, so a meat probe will just get in the way. When I do "stick it" I also go to the thickest part of the flat.
