Horseback riding for an hour and a half, my @$$ hates me right now...but it was so much fun.
The terrain varies from dusty paths to shallow streams and rocky roads. I'd consider myself a beginner as far as horse riding goes. I don't count horse camp 20 years ago to count towards "experience". But riding a horse is kinda like riding a bike. Once you learn you don't forget how to do it, but every horse is different.
We had a successful ride, seeing wild horses, a roadrunner (yes, they do exist but look nothing like the cartoon one), bald eagles and their nest, roaming cattle and waded on horseback through shallow rivers and streams in the breathtaking desert. I wanna move to Arizona!
