Household gas: rises or falls?

Does household natural gas pool in low places or rise to high places?
We have an occasional "gas" smell at the base of our internal stairs (we live at the top of them). I'd thought perhaps our appliance pilot lights and or ignition delays were leaking a little and it collected down there. The gas man came by and said that wouldn't make sense because the gas would rise. Now my desire to give the repairman specific hints to reduce his time/cost, and my scientific and practical curiosity are tickled.
Hints on identifying the leak source will earn extra points, but please be aware we know enough to have the gas turned off already, we'll be hiring a professional to do any actual work, and we'd just like to gather a little additional data before taking further and costly steps.
