I've noticed that sometimes when I smoke a cigar, it goes out on me. So I flick off the ash, and I've noticed that it's begun to tunnel. So I have to retoast the foot to get it to even out again. Could I be smoking it too fast? I don't think I am, but than again, I may be... But it usually happens once I get half way's down the stick it does this. Any suggestions on what I may be doing wrong? Thanks,Rod
