The forecast yesterday was for a storm to come in to Louisianna from the west leaving a 3-6 inches of snow. We figured we could still visit the national park and head west and not be in too much trouble and that most of the snow would come at night. It worked out fine for us. We ran into some snow on the way across Louisianna but it didn't really start coming down until we were almost to Tyler, Texas. It is snowing pretty good now (5:45 am) but I think we will drive out of the storm as we head NW to Amarillo today. We seem to pick the weeks with storms to travel west. Last year I-40 was closed for a few days due to snow/ice. This year it is I-20 that has the problem.
