just wanted to say hi...and comment privately on your post in the thread "anyone brave enough to post?"
You are NOT too fat to ride. It's all about how to carry yourself and your athletic ability. Athletic ability comes with time (and lessons, haha!) You absolutely don't have to be skinny to ride you just have to find a horse that is compatible with you.
please feel free to check out my blog www.eighteenhands.com to read my story as a plius size rider and to find resources for plus sized riding!
