Take a ride on the original hybrid vehicle: the mule.
Short of head and long of ear. A tail nearly bereft of hair. Small wonder the mule gets so little respect. But if there's a trail ride in your travel plans, you can't beat the humble horse-donkey hybrid. Mules offer a smooth and sure-footed ride, especially on rough terrain. And they have just one speed: slow.
