Erin Go Bragh is simply amazing. It awes me to see him in action!
On a serious note, though I did love the bass!... if they won't put you in your own age group then you may want to consider riding HC. Then, you won't be taking ribbons from 8 year olds
I did this at a hunter show once. I was doing the ground pole and crossrail division with 5 year olds and tiny ponies whereas I was on a 3 year old 17hh monster and I was 14 at the time! Haha. Made me feel a bit better about going, knowing I was riding HC
