Aussies first RV roadtrip in the USA

Now that I'm not running late to work, here are a few more suggestions. If you can time it right, you MUST visit the Grand Ole Opry in Nashville. The show is actually now held at the Ryman Auditorium, but if you like American country music (including Keith Urban :)) it is a must do. If you can spare the time or if you can't tour the White House, I'd visit the Smithsonian Museum, the National Cemetery, and/or the National Zoo (the Smithsonian alone can take days) or at the very least stroll the National Mall for a view of the diversity this country has to offer. Skyline Drive and Blue Ridge Parkway are gorgeous. Shenandoah National Park has multiple campgrounds (not sure how many will fit RVs), lots of wildlife and many activities. Gettysburg is also a must-see IMHO and you should be able to visit if you are taking the Journey Through Hallowed Ground. Once you get a better handle on where you want to visit, I'd post in the Campground forum for ideas on where to stay.
