"Dog Excrement Dispenser" -- that's just a dog :)

Yeah they came out with a feature where you can just paste a URL to something on openstreetmap.org and it formats it nicely in the output. So like if I type the URL to your profile page it looks like this: https://www.openstreetmap.org/user/molinamos

Anyway. I think having this on a single node is great. Because it's kind of one conceptual "unit"-- the dispenser and bin on a pole. But it's subjective of course.

Happy mapping! :D
