Try not to get gas in Pa or West Virginia. They are among the highest. On I-81 in Va at Winchester is a Flying J where we always fill up.Usually 50 cents a gallon cheaper than Pa. If you have the Flying J card it's 5 cents off gas and 8 cents off diesel.We like the campground at Crater Lake State park in southern Va. Nice pull throughs with water and electric.Also 2 Pa State parks we like are Locust Lake and Pine Grove Furnace. Both aren't too far off 81. Both have electric. Pine Grove has new bath houses.
