Ok so this is what happens when you A. Mess with jumping a 2'11" oxer when you and your horse have only ever jumped 2'6" verticals and B. Don't get enough impulsion over the first fence in the line and land crooked but then drive her for the very loooong 3 stride anyway!!
Basically my pony saved our butts...she knew she couldn't take a fence that height with the crappy setup I gave her, so rather than try and end up hurting both of us probably pretty badly, she just ducked out at the last minute...but because my shoulders were hunched and I was jumping ahead (which I am seriously working on!!) I ended up going on without here LOL
