Andrew, that's a wonderful trip report. Thanks so much for doing it. I've been through Albuquerque and I think even Santa Fe back in my touring days with the US Army Field Band (early 70s), but never for operatic reasons. An interesting set of operas, as that festival often seems to have.
As to Zdenka not having long hair: that tumble of suddenly released hair when Leonore or Zdenka reveals her femininity is undoubtedly visually effective, but I have sometimes found myself thinking, "You know, cutting your hair would be the easiest part of the disguise...."
Any Glyndebourne for you this summer, Andrew?
