Clearly a dragon is bigger than a horse and is capable of handling much more weight. It makes no sense that I can't ride this magnificent beast. You have people riding llamas, come on.... Gargoyles flapping around and still I am forced to run ahead of my beast that should clearly be able to out run me. Have you never heard of the Dragon Riders of Pern? You guessed it, they rode their dragons. I'm not asking for mind reading with them but my feet are tired after all these years of running!
