Which horse magazine should I subscribe to? I don't ride (though I wish I could)...

young rider is the best

Horse Illustrated is a good one. So is Horse & Rider.
But If you don't ride,Young Rider is good too.

I go horse riding and I read Pony Mag. So the best!

I read Horse Illustrated and its an awesome magazine it features all kinds of stuff and has a featured breed of the month for every issue :]
