I don't have an exact map, but it's on Peter's Run Rd., Rt. 88. Three miles from Oglebay Park, which is near Wheeling, WV. On one of the Oglebay maps, top right hd. corner, look for Peter's Run Rd. As you go up the hill, it's on the right hand side. The only place to park, is the neighbor's driveway. I forgot to get their house number. With it, we could get driving directions from map quest.
If you want more detail, email me at home.
Oglebay is a beautiful park. If you visit the area, be sure to see the Mansion at Oglebay. Inside it's decorated in "period" furniture and have a great many historical artifacts. I took the kids. They're not great history buffs, but they enjoyed it. Next door is a gift shop with beautiful glassware. Some it is hand blown.
