I've only been in 4h for one year, but I've gone for more than 6 years with my cousin (camping there for the week with her horses & helping).
I hated it. I was one of the only 4Hers who didn't own a peanut roller, so it made jumping clinics kinda interesting.
Nobody helped me with anything, even when I made a point to ask repeatedly, finally I just had to talk to my younger cousin a lot for tips.
I didn't win anything, but I didn't expect to. Athena was very green at the time, and I only took her through three classes. It was tiring because I only ride english with Athena, and there's only one english day here because there's not many people who ride english. It was like 90 degrees, so I took her through the two jumping classes, and called it quits.
She's very good, but the crowd is always big with jumping classes and Athena was afraid of the grand stands and kept refusing the jumps next to it, so no ribbon for us.
That was almost 4 years ago though, I plan on taking her again this year, and kick some butt in jumping AND speed events. 8)
