Routing
Bill,
I did the reverse of your trip about a month ago bringing a friend's RV-4 home from San Diego (Ramona) to Warrenton, VA (KHWY) just down the road from where you are right now. Good that you will be flying the easiest part of the trip first as you get to know the airplane and its fuel burn, etc. As you know options out west in the desert are much more limited as fewer airports have fuel.
Here was my routing - just reverse this:
Ramona (KRMN)
Imperial VOR (IPL)
Gila Bend Airport (E63) waypoint
Casa Grande, AZ (KCGZ) fuel stop
Casa Grande, AZ (KCGZ)
Cochise County (P33) waypoint only
Las Cruces, NM (KLRU) fuel stop and food on field
Las Cruces, NM (KLRU)
MOLLY Intersection
Salt Flat VOR (SFL) - this is Guadelupe Pass east of El Paso
Odessa Schlemeyer Airport, TX (KODO) fuel stop
Odessa Schlemeyer Airport, TX (KODO)
Mesquite, TX (KHQZ) - fuel stop
Mesquite, TX (KHQZ)
Clarksdale, MS Fletcher Field (KCKM) fuel stop and home of the blues!
Clarksdale, MS (KCKM)
Knoxville - Rockwood, TN (KRKW) fuel stop
Knoxville - Rockwood, TN (KRKW)
Martinsville, VA Blue Ridge Airport (KMTV) - fuel stop and food on field
Warrenton - Fauquier (KHWY)
A few notes:
Watch out for those restricted areas in CA/AZ/NM. This routing gets you through nearly all of that and away from the big tall mountains. Fuel options in eastern CA or western AZ are very limited... Like everyone said, try to plan out everything in advance and use a GPS. Big expanses of nothing-ness to go thru out there. Stay high as the desert winds can be quite extreme near those peaks.
Watch out for the ADIZ near DC and expanding P-40 restricted area right near Martinsburg. P-40 is Camp David, MD.
Also, sometimes the Piedmont area can be clear and the mountains obscured, which means that the Piedmont route can be safter. Other times it is reversed and you may want to fly down the Shenandoah Valley along I-81 as this is often a clear route with a number of airport alternates along that route.
Fly safe,
Rob
