That is pretty amazing your browser didn't crash! Or your computer didn't get restarted by some automatic update, or any multitude of other things that could have caused the window to close! It'll be awesome if you can make it to 2013!
A small clarification, only the 3 tutorial streets were possible for signpost hiding. The rest of the home street styles will have the signpost in the image (no way to have hidden that when taking snaps), but everything else including the house are not visible.
