Thanks all! Yes, I think he looks pretty in the snow even though it brings out his yellow much more! Not much I can do about that this time of year since it's too cold to wash him.
Thanks for all your encouragement all! I was quite pleased with him at the end and happy with myself for sticking with it even though it's been a long time since I've ridden on trails by myself. There are tons and tons of trails in this area - I could be gone for days if I wanted to. Most of them are snowmobile/4 wheeler trails so I have to be cautious about running into those, but if I go in the morning, there's almost never anyone out there. And Harley does well with vehicles, tractors, etc., so I anticipate he will be fine around 4 wheelers as long as no one does anything stupid (and knowing some of the locals, I wouldn't rule it out).
I was also happy I was able to stay on him easily despite the minor spooks and the occasional fast trot. And happy I didn't let him avoid things he wasn't crazy about at first. He is truly a delight to ride, like I'm riding on springs, even at his roughest. The only thing is, I realized I need my own saddle. My daughter's saddle is a 16" all-purpose English saddle and I think I need a 17". I'm hoping to buy one that she can grow into as well (her coach told me her 16" was ok for now, but that it wouldn't last her long). I hate to buy myself a saddle and then get my own horse next summer and it doesn't fit him. But on the other hand, it would be really nice to have a comfortable trail riding saddle (my daughter requires a jumping saddle). Suggestions? I don't care what it looks like, but comfort is essential. Should I just get a really comfortable trail saddle in a medium tree and hope I get a horse next summer that needs a medium? I really like a smallish horse so not likely to get a draft cross or anything! In fact, if I could get another Arab like Harley, I would jump at the chance!
