Had a good bowl of CH just now. Typically, towards the end of the bowl, I'll tamp to see if the smoke is done or not. It sure felt like I had a bit left. The top of the ashes wasn't near the shank. So, dry out the stem, tamp again and did a taste draw. Mouthful of ashes. Looked in the bowl and sure enough, chunk of the ashes were gone near the draft. And looked like there were good deal of ashes in there. I should have poke it with something.
