Ouch that sounds like it sucked! Congrats on the prolonged fall though! lol
I've been riding since I was 12 and I finally fell off at age 18 hehe and let me tell you it was probably the stupidest mistake in my life and totally my fault.

I decided to hop on my friend's horse, who he had just gotten that day, and ride him around bareback and only his halter/lead rope for control. And of course the horse spooked and took off and almost threw me into a tree but instead I landed in a pile of umm natural mulch and fertilizer... bleh

My friend was sooo scared that I hurt myself but I actually was dizzy for a second before I managed to jump right back up and start going after the horse so he didn't take off into the woods. And I too was told I fell very gracefully.
