We were at Coopers BBQ in Llano back in November (the day after the Sellards wedding). If you weren't wearing "RealTree" camo, driving a Pick'em up truck with "big mud tars" and four little bambi legs sticking up outta the truck bed, you were a "danged ol' foreigner!"
Well - guess deer season is over by February, so it should be okay
And sorry, I don't remember much about the parking lot, except that its on a BIG busy highway and wouldn't hold more than a couple dozen pick'em up trucks -- there may be space fore and aft for overflow but I wouldn't swear to it...
