Fast forward to July, 2011...as fate would have it, I no longer live in Chicago, now I live near Boston. The same friend (who is mostly responsible for turning me onto the Dead) just happened to be in town from Chicago on business. I took this as an omen and as an opportunity to change karma, or right a wrong, however you prefer. So I took him to the Furthur show in Mansfield. In addition to getting rewarded with a Scarlet>Fire (which he said alone paid the debt, we also got a tremendous Dear Prudence, which is a very personal song for him and put the show over the top - even though it isn't a Dead song.
So the Universe was restored. All is well. Karma. Thanks Furthur!
