So PHB page 181 states the next about using horses for travel fast: "For short spans of time (up to an hour), many animals move much faster than humanoids. A mounted character can ride at a gallop for about an hour, covering twice the usual distance for a fast pace. If fresh mounts are available every 8 to 10 miles, characters can cover larger distances at this pace, but this is very rare except in densely populated areas.", So I got a few questions, the characters must buy a horse every 8 miles and like leave (sell) the other one for the same price? (what if they love their horsey?? or they just dont have the money to buy a horse?) could they like, rent a horse??? just for that ride ?? it make some sense actually, I kinda remember reading about something similar in history of roman's roads if so... how much would be a fare price for renting a mount?Is there any guarantee for the business of seeing its mount again???
