Well, talking with my friends, looks like they're not going to be making the trip to Missouri, and we'll be meeting up in TX.
Depending on the weather and any last minute gotcha's, I'm looking at starting out Sunday morning and being at their doorstep Monday afternoon or evening, stopping Sunday night somewhere between Little Rock and Arkadelphia depending on how far I get the first day.
Barring any changes, I'll be going my usual route - I-40 to Little Rock, I-30 to Dallas, and I-35 down to Kyle.
Still have to change out the engine oil, front and rear diffs and transfer case with Amsoil, and change out the antifreeze. Don't look like the airtabs will be here in time, but I've got a plastic cardboard sign begging to be cut up for grill blockers.
As far as how long I'll be there - well, I'd say at least until New Years Eve (following Monday), or possibly longer for a good reason (such as a certain 8 year old begging me to stay another day or two - that boy knows just how to melt "uncle's" heart

), I've got three weeks to play with before having to be back at work Jan 14th.
