I don't ride due to medical issues and other reasons, but I have a pony and I do alot of things on leadline with him. I'm constantly trying to find new things to do with him, but lately i've found a ton of enjoyment in simply taking long walks on the leadline. It really gives you some good bonding time with your horse or pony, and it just gives me tons of time to think. I suppose riding is the same way. I wouldn't know because I havent done alot of riding myself since my health took a downhill turn but I used to trailride occasionally before I got my horse.
I personally get good fulfillment from the simple everyday barn life of grooming, feeding, leading etc and im working on other things such as lunging etc.
