Measuring distance by rolling a wheel of cheese would be interesting... the circumference would either drop as rind wore away OR it would increase as stuff stuck to the cheese and accumulated. So already we have sub-cheese miles, hard-cheese miles, and fuzzy-cheese miles. Then there's the stinkcheese league - the distance on a sunny day without wind that the average nose can detect its aroma. The Trebuchet Cheese League is not a distance but an organization of competitive flinging devices, so don't get that confused. The distance of a cheese thrown by trebuchet or catapult varies according to the host nation and region anyway, since the chosen cheeses change irregularly.

The Highland Games of Heathertop of course promote the length of a cheese-curling ice rink as a standard - which stretches the meaning of the term 'standard' since such ice rinks vary from about 22 to 31 meters, line to line. Cheese-curling has the unfortunate effect of promoting inedible cheese, since rock-hardness matters in curling. Proponents of the sport prefer 'long-lasting' to 'inedible'. As a side note, nations without a hard-cheese tradition have been known to substitute fruitcake, but that has never influenced an international distance standard.

I do enjoy old maps with a dozen or more competing scales. Seems like a great opportunity to do that on some of our Guildworld maps, even without involving cheese.
