My horse also spooked while on a trail ride. Never ride with a saddle that is WAY too small for you! I ended up falling off on my side (I fell off on my other horse 2 days before..) It sucked and I wanted to walk back but ended up walking back on him. He spooked AGAIN but luckily I held on. He was so scared. I feel though my confidence is higher because of my falls. I'm no longer that scared if I do fall off.
Every cowgirl has to fall off one time or another!
