You have mapped not 6 but 11 horse highlines and tagged them as riding centres (and once you have mapped a riding centre correctly: https://www.openstreetmap.org/node/12496714162). And you only started with OSM 2 months ago. How are you going to continue? Should the whole of the USA be covered in incorrectly tagged horse highlines in a few years' time? The more often a tag is used incorrectly, the more useless it becomes. I don't know of any tag that is intended to make any text appear anywhere on the maps. That is not the principle of how OSM works. The notes are readable for humans, but cannot be processed automatically.
