I saw the smiley, but couldn't really tell what it means (besides the
smiley :)

E.g. couldn't it be that while the burning part of the gas floats and
dissipates quickly, the stinking part doesn't, which could explain the
stinking neighborhood? Don't know whether this is the case, but looking at
what's in things is often an eye opener. (Highly recommended with food...
