I bought a really good one, doesn't even require gas!
I was made of a cloth material, had 2 sleeves, and kept me really warm, I believe
you can also get them in the wrap around kind without sleeves, and these can even be
used together for more than one person...hmm..warm
Patio heaters guzzle gas, the vast majority of the heat is lost to atmosphere,
and in a world where fuel is running out, and the planet is moving towards
a spiral of runaway weather, shouldn't we be acting a tad more responsibly?
Sad thing is, we are leaving this world soon, but handing it to the next generation
in a worse state than it was handed to us.
