Welcome! If you check back on the previous page at Post #1299, you will see a list of markers scheduled to be replaced. Some I know are already in place, others are still not replaced yet. It's a coin toss on most of them until the crews get out with nicer weather to work on them. The DOH folks that I spoke with explained that given the choice of plowing snow off highways or replacing signs, the plowing takes priority.
Anyhow, there is also a spreadsheet that you can print off and keep with you as you travel. I've stopped at several, only to find out vatrader01 or intothenew/outwiththeold already posted this one. Oh well.
One that is available in your neck of the woods is Rt 50 at the Grant / Mineral County line. I've been by there twice in the minivan.
Enjoy, and remember to take time to research and write up a little bit on each marker. (See notes on the first post for general guidelines).
