You and me both. The closest I got was in the 90s when I had range of B&W landscape posters and was represented by the same people who sold AA's posters.
I was in the 'States in 1978 when AA was well and truly alive, apparently in those days you could just rock up to his house at sundowner time and chew the fat but I didn't know that at the time. Man I would love to have done that.
I'm more into wildlife photography with DSLRs these days but do miss the more contemplative approach of large-format B&W. I find doing panoramas is similar in that it requires time to set up the camera, get exposure readings etc etc. I still have my Tachihara
but can't see it ever being used again.
