I've been lurking on these forums off and on for a couple years now, and only recently discovered this board. Here are a few pictures of me onboard, first from my barn's Labor Day fun show on my new boy Tyson (we won 1st place in Hunter Hack, and 2nd place in Fun Over Fences among my cohort of extremely non-competitive adult riders!).
I'll also include one with my on the horse I bought but wound up not keeping, Sugar. I bought Sugar from my lesson barn, but she went lame and was diagnosed with navicular within a week of writing the check. They gave me plenty of time to see if she would come sound(er) with corrective shoeing, but after a couple months and not enough improvement, they took her back and helped me keep looking for an alternative. In the end, I think Tyson is a better fit for me. He's a nice big 5-yo never-raced TB (16'2), vs. Sugar, who is about 15 years old and only 15'1.
I've been slowly but steadily losing weight since I started making an effort in February. From a starting weight of 221, I was probably about 210 in the bottom picture with Sugar (early April) and ~192 in the top pictures with Tyson (early September). I'm down to 180 as of today!
(Hopefully I can get the image attachments to work!)
