I had already decided to go to Guadalajara to hear the Jalisco Philharmonic Orchestra after hearing a live concert a few Sundays ago on Puerto Vallarta´s local cultural channel 13.  I missed going to classical concerts, and I had not been to Guadalajara recently.  However, events intervened, and about the same time that I realized the Guadalajara trip would be a little ambitious, I heard about the Puerto Vallarta Chamber Orchestra (PVCO) performance at the Puerto Vallarta Hotel Krystal conference center.  It was clear from some on line research that the level of musicianship might be a little bit . . .
