San Ramon has open gym at Gale Ranch Middle school on Tuesday evenings (6-9) and Sunday mornings (9-12) for $5 Can you please add it?
I've returned and have updated the map. I've removed all the schools and community centers until I can find more information on dates and times for them again. I've also updated the list of dedicated badminton clubs. The major ones that I've found have been added and the ones that have either changed ownership or have closed have been removed. I also added places that are just badminton stores. Please let me know if there's anything to be added.
