I always thought "Clyde" just had to do with the fact that his markings look like a Clydesdale. He was stocky, but never looked so hefty to me when he was racing. It used to be really common for stallions to put on weight, but with all the health risks, most people are more careful about that now. On the other hand, even healthy-weight stallions often look bulkier than they did as colts. It's hard to know for certain with still pictures. I also can't tell much about their mood without seeing them in motion. They don't seem sad to me. They seem to be taking an interest in their surroundings. Maybe they were worried about the storm front that was coming, and that's what you're picking up on, VA in CA.They are wonderful pictures.
