Which would you rather breathe: CO2 or Ammonia?
Breathing either one will kill you. I'll stick to plain old air thanks.
Dave, I see your point, there is so much done to our food its hard to know whats safe and what isn't. Hard to believe they would allow something that really bad for you to be sold on every corner.
I'm kind of a taco purist, I only like my own homemade ones, so I've never been tempted to buy one as fast food. Gotta say though, the fast food cart idea appeals to me on many levels. Its not something we see here in Edmonton much. Not sure if thats because its so *bleeeeeep* cold most of the year or that no one has really thought of it but not too many food carts around here. *Sigh* I'll have to go visit some of our members in the US to try it out.
