Last night I smoked a Vegas Cubanas delicias, or rather I tried to. It was fine for the first two inches or so, then began to tunnel horribly. It began to take two or even three really hard pulls to get the wrapper to burn, and then it started getting quite hot and nasty. I chucked it with a good three inches and change left. I know the cigar was not too wet, as it's been in my desktop for a month or better, and it's always at 62-68%. It was oppressively humid last night, so I don't know if that may have had something to do with it, or if it was just bad construction. I've smoked three or four of the same cigar, out of the same humidor, and never had burn problems before. Oh, well, it happens once in a while.
