Like everything about NYC, the subway is a love-hate relationship. But overall, it is a very easy means of transportation. Navigating the subway system is far easier than navigating the streets with a car, IMHO. Everything is labeled, there are only two directions, and there are maps everywhere. So I generally don't understand why visitors take cabs because they aren't sure of the subway.
Except the other day, I paused to re-think that perspective. I went uptown to go paint in the park. To get there , I had to take the A/C uptown.

The train came and I got on it. Except this was the train that arrived. And it really wasn't an E train rerouted on another track. It was a substitute C train pretending to be an E train.

Except when inside the train, passengers were advised it was a Coney Island bound F train that was currently in Brooklyn.

So, way to go MTA.
I am a local so I didn't get lost. The crazy train took me all the way up to the park where I had a peaceful afternoon painting.
