Amy Dixon, thank you for the info on the butane stove. Never thought about that. It would be easy to ventilate so I could use it inside. Also I have a wonder bag and love it. I have been playing around with the idea of seeing how easy it would be to make one. They are a bit pricey but not to bad. I have never heard of an HERC-type oven fueled by candles. Sounds interesting so will check into it.
OldmtWoman you and Amy both please be careful in that snow. As it melts and then freezes it can become ice. Don’t need anyone slipping and falling. Stay safe.
