RGS Grade - Vance Junction to Butterfly Trestle *LINK*

I've been playing around with MS Virtual Earth and have put together a map for a portion of the RGS. The map has the approximate grade highlighted in red. I've also added push pins to mark approximate locations of bridges, mileposts and structures.
If you get a chance give it a spin and see how it works for you. I've had 1 report of push pins not working in Firefox. I use Firefox and it seems to work fine for me. I'm also not sure how well it will work on dialup, I recently moved to DSL.
You should be able to drag the map around with the mouse. It will zoom into a scale of 150 yds before you lose the map image. MS doesn't have the high resolution data available in this locale.
