Well, I don't have any from my first lessons readily available, but I do have some old ones.
This was my first horse, at her first show. It ended with the horse spooking and bolting and us being DQed... That's pretty much how every classes ended with us. I was never able to successfully turn her into a show horse, and that's probably because green rider + green horse = a really bad idea! I was 13 in this picture and I had only been taking lessons for about 2 years, on nice well-broke school horses. >< http://i3.photobucket.com/albums/y52...ps7f0f889a.jpg
This was a few years later when I started showing my dad's horse. This horse should have been my first horse. She was enough of a challenge for me to learn on, but was not too much horse for me. I had a blast with her. I did eventually give her back to my dad, and he still rides her. I was maybe 15 or so in this shot. http://i3.photobucket.com/albums/y52...ps1c04bf65.jpg
Here's one from that very brief time I showed western. Again, I was about 15 years old. http://i3.photobucket.com/albums/y52...psdcbe6054.jpg
For reference, I'm 25 years old now, so these shots are 10 or more years old.
