Thanks Chris, Lesley, Davie!
Yes, Chris, I did bring a tripod with me. I have three tripods and brought my smallest one. But it's really too small and light to support the weight of a full frame DSLR and a TS-E lens. The thing wobbled terribly and it was a challenge to work with, to put it mildly. I'm actually pleasantly surprised that I got any photos at all out of the experience, considering how miserable I was at the time, dealing with it. Goes to show...
