I'm keeping my grill temp at 260 (upper rack) as measured by my temp
probe resting near the brisket with the tip elevated off the rack and
not touching anything.
That temp requires that I have the off-side burner set to just above
low.
Problem is, my chips aren't smoking in the envelope - which is on the
lower rack. I tried tossing a few on the "char diamonds" below the
lower rack, and still no smoke.

??????????

Thanks

Mike
