We're driving from CT to Las Vegas for family Christmas visit. Leaving day after T'giving and would like to arrive in Vegas around 12/11, spend couple weeks & head back 12/26. Will need to hoof it back by 1/3. Did this summer of '02 and went thru heart of the country... best trip we've ever taken! Because of early winter, this year we're going southerly but don't know much of what to see. Plan to see Valley Forge, Blue Ridge Hwy, Smoky Mts., then ???

Only other thing we "must see" is Grand Canyon, just not sure of best route between. Considering AL, MS, LA, TX (I-20), or AR, OK, etc. (I-40). Biggest concern is winter weather. What to expect? What to see & do? Also what to focus on in VA/NC/TN? Any favorite places out there?

One other bit of info: it's my wife & I and 3 kids (10, 5 and 2). Hold the negative comments...they're great, adventurous travelers (the little one did well at 6 mos., but now will be TBD). But we're creative there. Thanks!
