I tried last night and failed. In the last few weeks we had two big dumps of snow and -20s temps. Then it warmed up to +5 for a few days. Then rain turning to snow and temp falling into the -20s again. My propane tank ran dry just as I was putting the sausages on the grill. When I tried to pull it out it was frozen in. We were in a hurry to eat and get to my stepdaughter’s band concert and it was too cold to fight with it so the sausages went in the oven. Natural gas sounds better all the time.I’ll BBQ all year round. I use natural gas though, no bottles to worry about!
