Hey John,
In that condition I don't think even Otto Perry would let you go out and take pictures of trains with him.
When you get back under the layout can you see what you can find on Marshall Pass trackage, maybe Sargents to Mears. I think you mentioned before that your posts on that line ended when you had to get more material from under the layout and your back was out.
Hope you recover quickly.
Regards,
matt
