Get off usenet and call the gas company emergency line, leaks only get
bigger. A house here blew up about a month ago (Frankfort IL) at 5:30
AM when the owner (they think) flipped a light switch. The house was
completely gone and the explosion heard for a 4 mile radius, adjacent
houses were seriously damaged. NG is odorless so they add a chemical
that smells like the rotting cheese you described.

Here's another- propane, but same scenario & result-
Johnstown NY- Oct 14

[and searching for 'propane' on my local news channel turned up
another explosion in Sept, & one in August. Don't screw around. The
gas supplier would rather make a lot of nuisance calls than lose a
customer.
