It's about 75F here and we aren't expecting it to get really cold until Sunday. The word I hear was that it might, just might, go below 30F. ...
I'm laying extra water so I'm covered if the wells freeze or we lose power and the pumps don't work.
I lived in Northeastern Pennsylvania for many years with a well that's wellhead that extended up about 18 inches from the ground. It regularly got down into the single digits and often below zero, dand I never had my pump freeze. One year it got buried under so much snow that I didn't see it until late April, and still no problem. Maybe I was lucky, but I never heard of anyone having that problem.
Cash on hand in case the telcom/satellite credit card system fails.
I always have some cash stashed (not much point in putting it in the bank at 0.5% interest and then paying $2.50 to get it out through the ATM). I have some cash in each of my and my kids EDC kits and BOB's. I rarely have less than $100 in my wallet. I also have a bunch of cash in my safe at home (good for paying/tipping tradesmen for emergency repairs). I didn't think about taking any extra out because of the snow. I guess if we got two feet of snow the local banks might have stayed closed for a day or two and ATM cash supplies might run out, but I don't think that would cause a shutdown of the whole system. But why would you stock extra cash just because it's a few degrees below freezing? You Floridians must really have some thin skin! ;^)
