Too funny Bob.

Chess. My objection is to the absolute mantras one finds on bbq sites: "You can't..."

Michael D's FIL most definitely can, even if he does not really know what the actual temperature is. It is a skill he has refined over many years.

Now if you were to say "It is very difficult..." I would agree. I don't plan to abandon my thermometer (which is probably out by at least 5 degrees in one direction or the other) any time soon.
