The 6 bar is a jump-off competition where nothing but height matters. It starts off with 6 jumps, each jump being slightly higher than the last. After the last fence tops out at over 6', the first two jumps are taken down, so the teams only jump 4 fences trying to top out at the highest height.
Anyways, here are the photos from that night.
The first two riders crashed and burned; I've never seen anything like it...! It's rare to have a horse full out crash through a jump, much less the first two horses in the order of go on the first round.
Some of these pictures really don't show my photography skills well at all, but I thought they were interesting shots regardless, and worth showing:)
