Nobody intends to tumble from the saddle, but if it happens, let it be with AA-D Horse Adventures. An amiable guide will dust you off, explaining what caused your abrupt dismount and how to avoid future falls, taking care to minimize your embarrassment. Then, as in the proverb, the group leader will help you back onto the tamed beast. With names like Little Tree and Cowboy, these horses are well groomed, responsive (if you can communicate clearly), and younger than the plodding types found at many horseback-riding outfits. Tree Tops' extensive trails meander through live oak forest, around wild coffee shrubs and Brazilian pepper plants, tempting the ever-hungry equines and keeping you alert. "Toes up, heels down," the guides nag, while praising your improved form. You survive the rest of the ride without kissing the dirt again, and the horse is replaced by a soreness that smacks of a more amorous adventure.
