We drove back to Toronto.
This heater shows no open flame and gets quite hot but won’t set things on fire. You need a well ventilated place to use it, not a tent.
If you don’t have the bolts and washers to assemble this, one flowerpot and three or four stones would be better than an open flame.
See the flowerpot heater video!
We visited the Luray Caverns in Virginia. They’ve been known since the 1800s.
It was fascinating, with curtains and piles of calcite and other minerals.
I found this gem in Oakville near the lake shore.
