Regardless of disability, the public transportation system here is not great. I would suggest you minimize your reliance on it as much as possible by being able to take single lines to your most common destinations. This will save you many headaches.

I can’t say I’ve paid close attention to how prevalent ramps are. But I feel like the city as a whole could be doing a lot better. Lots of businesses have stairs or thresholds of some kind.

Strangely, the city itself is making improvements by replacing nasty sidewalk sections. There used to be some pretty extreme sidewalks that were a hazard but many of those have been tamed. And sidewalks by intersections are much better with the ramps to street level. I say this is strange because normally the city is dogshit terrible at everything it does, but not here. I won’t say that it’s the most friendly city for you but progress seems steadily moving in the right direction.
