Oh and check this out - horse ownership costs in Hawaii:
You can buy a pretty good horse for forty or fifty dollars, and a good enough horse for all practical purposes for two dollars and a half. I estimate "Oahu" to be worth somewhere in the neighborhood of thirty-five cents. . .Williams bought a handsome and lively little pony yesterday for ten dollars; and about the best common horse on the island (and he is a really good one) sold yesterday, with Mexican saddle and bridle, for seventy dollars - a horse which is well and widely known, and greatly respected for his speed, good disposition and everlasting bottom. . .You can get a horse for a song, a week's hay for another song, and you can turn your horse loose in your neighbor's broad front yard without a song at all -- you do it at midnight, and stable the beast again before morning. . .
- Mark Twain, Roughing It, 1872
