2" of snow in texas would mean a lot of accidents. People down here do not know how to drive on ice/snow. Last year, we went out in the snow to my buddys house, (roommate has an avalanche) and we witnessed 4 accidents within just a few blocks of each other. This was also at night and not many cars were on the road. we stopped to make sure the drivers (mainly girls, true story) were okay.
Preppers show on Nat Geo is pretty interesting, but I agree, a little overboard. There has been some great ideas- like the gasifier- but I dont plan on changing my backyard into a mini farm and I'm not going to start raising chickens.
