I am currently running a campaign with one player running a typical halfling theif. Because we have been playing alot of outdoor type adventures (with a lot of travel involved) the player is complaining that he should be able to ride a horse. We looked for any ruling to this effect but did not find any (quick search during play). Logic notwithstanding regarding how a 2'10" halfling would ride a full size horse I would like to find a rule spelling out the issue. Don't have access to the books right now and would love to have an answer for the player. Oh if there isn't a rule then suggestions on how to handle the situation would be great....thanks.
