Just deployed v1 of a site which lists outdoor gyms. Data: found various maps online which I combined.
Planning to add posting new places, and more details/filters/pics.
This is maybe the fastest I've launched a project, just a barebones meteor+react app which I can build upon, not even any analytics on there right now.
I'm playing with the concept of super-super-mvps, just getting the most basic thing online to keep the ball moving.
