I see cross counrty as an opportunity to improve my riding and my horses agility. Go big or go home is the way i see it :p
Course not. If you and your horse love what you do just do. You don't have to compete if you don't want. Do what you want and what you love.
Depends on what you want to get out of it-I show hj but school cross country for fun and do dressage training for my horse's benefit
