I ever got an experience to visit one of my relatives which is very rich in the country. This family has a big ranch and a lot of horses. Actually horse riding is their lifestyle. If you have many champion horses, you might also like to invest for buying some horse riding equipment like saddles, saddle blankets, stirrups, helmets, lunge whips, stirrup pads, lunge lines, and horse rugs.
You call this lifestyle as equestrian. It is somehow need a passion for taking care of horses, not only spending money to buy horses and all the equipments.
