As an active library user w a 4 year old and 1 year old going to the bathroom at the sf library wasn’t a good situation- so for many folks (disabled, those w young children) the library was not available to them.

And yes, with children access to a bathroom is necessary.

Also now elsewhere and going to library is so fun. We can bike etc. they are reasonably strict though. No sex, drugs, sleeping etc
