What are the best websites and techniques for advertising a pleasure horse for sale? By pleasure horse I mean one that is fine for some trail riding, some flat arena work, maybe a little dressage or western, nothing too serious.

I'm not looking to make money or anything, just find the amateur who wants a cute, friendly, sane, horse to play around with on the flat. The price is just to weed out the crazies that I wouldn't want him to go to. I and most of my friends compete and we don't have a lot of contacts who just ride around. My little TB is too young and fit to be ready for full retirement, but needs a less stressful job than my competitive aspirations.
