Jan,don't know if these are "must sees" but IMO are worthwhile stops if you're in the areas.
Wash,DC area:
1. Mt Vernon estate,home of George Washington. A good motorcycle ride along the Potomac river on the George Washington Memorial Parkway.
Parkway deadends @ the estate. Favorite time to ride it for me is a Sun. morning in the Springtime 6-7 A.M.. Not much traffic,good scenery.
2. Great Falls Park on the Potomac river. Accessible from either Md. or Va.,as 1 side is on Md the other in Va.. I'm partial to the VIRGINIA side myself. :lol: Wild rapids on the Potomac. A favorite of kayakers.
Virginia:
1. Natual Bridge,Va.,just So. of Lexington,Va. on RT. 11. Great motorcycling roads all thru this neighborhood.
2. Luray caverns,Luray,Va.. Good scenic roads,Luray is small quiet town to relax in. River rafters & outfiters are available here.
3. Jamestown,Va.. Take the FREE State run ferry to Jamestown on a clear day.
Maryland:
Eastern Shore. St. Micheals Island, Maritime musem. Chincotinque/Assateage(sp?) Islands. Lots of stuff to see over here.
Kentucky:
Louisville. Gotta go to the Louisville Slugger bat company.
Canon City,Co.. Skyline drive. A 6 mile roadway that is a must do.
Hanksville,Ut.. Goblin Valley state Park. You'll think you've landed on another planet.
Nevada. Ghost towns all over the State.
I coulda posted more,but these should keep y'all busy for awhile.
It's a BIG Country!!
