@fimm Thanks, have updated the Ryries rack on OSM.
Fences are a bit complex, the manual says:
bicycle_parking:informal: Notably large or well-used railings, fences, or other street furniture which nobody objects to having bikes chained to for short periods of time. Don't use for every railing or street sign, but only for long-ish runs used by lots of people. Judgement required!
(https://wiki.openstreetmap.org/wiki/Key:bicycle_parking)
I'd say at this location, given that official parking is nearby, I would not add the "informal" fence parking, this is perhaps more for locations where it would be the only option.
What do other local OSMers say?
@rbrtwtm and @chrisfl Thanks for the tech info, that's useful to know!
