Sense of a spark

My house smells like a gas station and it's freaking me out a little.  I've already called my dad and let him know and he thinks it's probably from a leaking gas can in the garage but (because I'm crazy like this) I'm still worried the house might explode.  And of course my bedroom is right over where the leaky gas can is so my previously minor headache is getting bigger.  Thankfully I'll be leaving in a few minutes to go pick up my mom so hopefully it will diminish in that time.  But, for now, I think I'll go find the place in the house furthest away from the garage.

Edit 4 hours later: The gas cans were moved outside to the back porch about 3 hours ago and the house is almost completely free of any gas-like smell.  (The garage still smells some but that could also be due to our gas heater & water heater.)  My headache thankfully went away but it was this close to coming back thanks to our not so lovely Red Robin dining experience.  *sigh*  Today has not been a good day.
