I am leaving for Talladega in the morning and will be back next Monday to check my emails. That is if I don't get blown away or drowned along with 50,000 other people camping out in the fields around Talladega. If anyone is at Talladega come by West Campgound A spot 312 & 351 and say hello. Might even have a few cold ones for you. Hardy
