[TheForge] Orange smoke (was: Petrogen Torch Yak)

[Jerry Frost]

Makes sense.

Thinking about it I don't believe it stayed orange very long. The demo took
place behind a chainlink fence along a busy street. If there were clouds of
orange smoke drifting across the Old Seward Highway in mid-town I'm sure
there would've been comments, probably traffic accidents. Anchorage drivers
are easily distracted. <sigh>

The vender's building and the one across the street are white, I'm sure
orange residue would've been obvious.

I think you have a most reasonable explanation for the "smoke" color.
