hotrun, you are just like me. I grew up "Eventing' without even realizing I was doing what I was doing. I just thought I was jumping, but instead of the fancy jumps I saw on TV, I was jumping fallen trees and stone walls and creeks and all that whohaw. Who knew what I was doing was a real sport - then I figured it all out when I joined Pony Club.
LOL, I would of just taken that as very solid and secure in my tack, with a very solid and secure seat - all the while remaining defensive. That's ok - my coach says I have the typical eventers release.......non existant. lol.
Brighteyes - GO FOR IT! If it is something you want to venture into, do it. Make sure you purchase a Certified and Approved Vest if you want to start Eventing. Intec Flex Rider is the cheapest, and it has the stamps of approval right on the vest. Meets both ASTM and BETA standards for the level of protetion needed for eventing.
If you choose to sign up for the clinic, just make sure you are honest and forthwrite about where you stand, and the Clinitian will work with you to the best of their abillity.
Don't be nervous, just make sure you watch, observe, listen, hear, and ask as many questions as you can - afterall, it is your time, your money and your education.
Get a hold of your local pony club! I bet that would be a great start!
