Thanks to a great suggestion by gimmeslack, I have added a link back in the original post (#1) to 3 webpages I made with all of the known Markers in WV.
It's divided into 3 pages (A-H, J-O, and P-W), but I've added enough links to hopefully make navigating easy. As the markers are posted, I will try to note it on the list so you can easily see which ones are "unclaimed".
Brush the snow off the bikes and let's see how many we can find before Spring. There's bound to be a few near you. Sure beats sitting around watching reruns on TV.
EDIT - 15 JUNE 2009: Marker database is now on a Spreadsheet. Click link in my signature block or on Post #1 to view.
