I pulled up a map on Yahoo and it looks like the beginning of the route that makes the most sense is to hit I-81 down to Knoxville, then I-75 South, down through Chattanooga, to I-59 to Birmingham and Tuscaloosa down to Meridian, MS.
After that, depending on where people are, it can either pick up I-20 to Jackson, MI, then hang a turn south from there on I-55 until it intersects with I-10 on toward Santa Fe, or alternatively, stay on I-59 down to Gulfport, LA, then pick up I-10 there toward Santa Fe/Houston.
I could potentially do the first leg of it. Maybe from Fort Washington, MD to Gainesville/Hay Market, VA (or even Front Royal if it's necessary)? Heck, if one of the girls in the Manassas area can pick up a piece of it (Skittle, Nolu?) I can give you gas money...it's the time thing that is tight for me.
Fort Washington to Gainesville is an hour one way. To Front Royal it's 1:45 one way.
Sounds like the MD/VA leg is covered (and my car is too small) but if a stop over is needed, she can stay here for the night. I MIGHT be able to arrange a stopover in Danville, VA if you end up going that way.
Yeah, Ft. Washington isn't that far--it wouldn't be a problem to pick it up at the door. Is there a day/time for this? I work full time, so weekend is best, but I may be able to get away with a Friday.
