Don’t remember the date, Euan. I do remember the reason. We had some visiting friends that were big birders. They wanted to see the Elegant Trojan which, at the time, a few would come up to the Huachuca Mountains in AZ to nest. We took them there and a few other places in the area looking for birds. Missed the Trogan but the trip made me realize how I could combine walking in nature with birding. It took me another 5 years before I saw a Trogan!
Found this forum shortly after the visitors left.
