Most of my city is laid out in gridded blocks except for one part (Murray) that was developed in the 60s. There are heavily-travelled north/south streets and some that are less heavily-travelled that make good bike routes but most of them do a weird bend when they enter Murray - kind of like a black hole of linear travel, with roads that loop back on themselves, cul-de-sacs, and dead ends. I spent hours with Google Maps trying to find good way through this Alice in Wonderland maze, and thought I had found one only to get there and discover that a street Google Maps thought was a through street ended up dead ending on both sides into a creek with no bridge over it. This means that I have to bike on a horrible crowded "fast" east-west street (45th South) for a few blocks before I can get to a through street again. I just ride on the sidewalk, slowly, and hope nobody notices.
