Frances, Thanks for weighing in, and for your commitment to this issue for 40 years.  But with all due respect, I think your POV might now be so locked into the vision you have supported for so long that you might be ignoring, or simply unaware of, many changing dynamics that might make past arguments in favor of rail less compelling-- as we move further into possible futures-- than they may once have been.  But rather than repeat myself, you can read my other comments in this thread if you are interested in better understanding my thoughts.  If you are, please feel free to then critique my thinking if you have the time and interest.  Aloha:)
