Which Bridge?

I have loved this saying for ......... well forever.  I had it as my signature for a very long time, that is until I thought I was going to be a "for profit blogger" - which isn't really working well yet, so I may just go back to it since it is part of me.

What do you think?  Have you figured out which bridge?

I know I'm still figuring that one out.
Hopefully I haven't burned too many of the "wrong" ones yet.
