Can I still use my propane barbecue tank in the winter?

You can like the others have said, Unless you live in subzero weather that is. Propane boils at -40f and slows it vaporization down before that ! But all is well if your not that cold ! A strong drink does help and make it more enjoyable ! We get two season here, Winter and getting ready for Winter ! Not that bad really ! From Vermont Happy BBQ~!
