We've been smelling a very faint gas order outside. It comes and goes
so it is hard to locate. We don't smell it inside the house at all. We
do have a gas furnace, water heater, dryer and fireplace. None of
which is on when we smell the gas. Since it isn't a consistent oder I
am not sure if the gas company will be able to locate where it is
coming from. Is it possible to be smelling the unignited gas from a
neighbors furnace? We seem to notice this oder the most during this
time of year. It does make me nervous cause I am not sure if it is
dangerous or how to find out what it is. Should we be concerned?

Plenty of other good posts. As said already: Do call the gas company.
I have an interesting story.
Same deal - faint odor.
Called gas company. Quick response. Had a sniffer.
No luck finding a leak in the house or at the meter area.
Tech sees a pipe going into the ground. "What's that for?"
"Goes to the gas grill over there"
Tech takes a cigarette lighter and ignites the the leak at ground level
where the pipe had rusted out!!
We capped the pipe.
