Brian, awesome report. Thanks for posting that.
I've got the raw data for Missouri and Arkansas, but my computer crashed a few days back, so there will be a delay before I get it organized and uploaded. Fortunately, I didn't lose any work in the crash. Just a matter of re-installing Windows and starting over.
Coincidentally, I'm headed to Louisiana today. Not sure how much (if any) of the Louisiana portion I'll be able to map, but I've copied the Vertices route to my GPS just in case. I tried once before to map the Louisiana route and if I remember, I got mixed up because the signs on the route didn't match the rudimentary MRT maps they used to have posted.
