good luck you will be fine someone took my exracer to one the other week and it was his first ever show we was expecting him to get all excited thinking he was at the races but he was as calm as anything and he won it
I know the feeling, I have a show jumping course planned for the 20th of this month... I'm really nervous even though I probably won't be jumping anything over 2 foot! (It doesn't help that I haven't competed for almost 5 years and the horse will be attending it's first show at it's new home, we don't know if she has been competed in the ast either!)
