The big news coming out of Kentucky should be all about the rounds, the rails and the leaders after day one of the 2011 Adequan FEI/North American Junior and Young Riders Championships. But these are the dog days of summer, and in Lexington, Kentucky, those days are stifling. At 97 degrees and high humidity, the juniors competing this weekend are battling each other, and the heat. Hunt coats were excused yesterday during Round 1 of the show jumping, but the heat didn’t stop Kaitlin Campbell of Zone 3, who led the day in the YR division, or Sydney Schulman, leader of the Junior division. Thanks to MacMillan Photography for sweating it out onsite at NAYRJC this week. They caught the opening ceremonies, the golf cart parade on Wednesday, and they’ll be there until the bitter (and hopefully cooler) end on Sunday
