I was looking up information about state parks for wv and found that they are participating in geocaching. I am sure other state parks are doing this as well. What a wonderful family vacation/weekend activity or day activity if your close by. They have a link to the offical geocaching community site if you want to look up more information for your area. Fun, Adventure, Mystery, Hiking, Technology… what more could you want in a family trip. Just watch where you dig.
