And here are my subway photos on the 6th.
So I started by taking the F train. The first picture is shown in the first post.

This is useless as a texture, but if anyone thinks it's useful then sure, go ahead.

Then I miraculously bumped into an R68 G, right after the F left. The fourth picture is the picture of the G at Church Av, also shown in my first post.

Took the R68 G all the way to Court Square, where I just took pictures.





From there I transferred to the E and took it to Queens Plaza. The next three photos were taken there:



And then I took the R to my destination.

So far, there are only two sets of R68s that I saw are on the G line.
