When you have to go get Sonic and it's -10.7 deg

My wife and I flew into Chicago O’Hare yesterday to spend Christmas with our daughter and son-in-law and the grandkids for Christmas. We left SoCal and its 64 F for Hobart, Indiana and today’s 4 F temperature and snow falling to the ground. It is COLD!!! I can’t imagine going out for a Sonic burrito in this environment but what does a sunny guy like me know? When the bitter 55 F cold snaps roll into SoCal I have to but on a long sleeve cotton t-shirt and wear ankle sox with my sandals.
