The spikes on Rhaegal's back are sleek and while sharp, without ridges. It's difficult to get a firm grip without slicing your hands open, even while wearing gloves, so he's mainly holding on with his thighs. Holding steadfast like riding a horse bareback while it runs at a full-tilt gallop, only faster and far more dangerous.

Used to following, Rhaegal trails in Caraxes' wake without any coaxing needed from Jon. It's farther up than Jon's dared to go, and while there is a small Ned Stark sounding voice in his head reminding him of the danger, the thrill is much more appealing.
