Darn it I had a computer crash a few years ago & lost all my pictures & videos. Yes I have learnt the value of saving things like this to disc people!
I had a brilliant video of me jumping a speed class on my horse Barney, also learnt a valueable lesson that day tighten your girth before going into a speed jumping class.
So we got round nearly half of the course I spun onto a double disaster saddle starts to slip on the first fence, I end up sideways offski I go & Barney carrys on to jump the last fence of the double, stops looks like what on earth are you doing on the ground.
I am fairly certain my old instructor should have a copy of this somewhere but have lost contact with her. Mental note should search her out, would love to have it back was freaking funny.
Nope, it is horse poop! Where we live the ground is rather hard, crappy clay, so to soften the ground we use manure, we had only just put that down that morning, hence it hasn't really broken up :S So on either side of most of our more permanent jumps we dump manure to make the take off and landings as soft as possible. We did have some sand dumped in one end of our arena, but it was sooooooooooooooo expensive!!!
