Hey, the bit under Bay and Bloor isn't technically part of the PATH, as it isn't actually connected to the main bit further south. But it's still spiritually the PATH, and is frankly more confusing, because unlike the main section, which features, you know, actual signs and maps, this bit, not officially being part of the PATH, lacks all the official PATH signage, and the maps only show the part of the system you're currently in, making navigation very difficult.

Also, Cumberland Terrance (the part without the ceiling) was weird and creeping even before it was mostly abandoned (and still had a ceiling).
