Hey, I work thirds and there is just about nothing better in life then showing up for work an hour early and smoking a bowl in my car at a nearby car pooling lot. Unfortunately tobacco isn't allowed on the property so that means all the cigarette smokers have to walk across te street on their lunch break to smoke. It's really kind of stupid. But I was just wondering with winter fast approaching is it bad for the pipe to sit in the cold car for 8 hours while I work in a Michigan winter? I only have 1 pipe right now and the sentimental value is through the roof, I would hate to kill my pipe. It's a cob if that matters for anything.
