Speaking as a rural volunteer firefighter/EMT....
One of the easiest things you can do to help your family in an emergency is to have a house number that's easy to read from the street. It's frustrating for everyone involved when we're delayed because we can't find the address. Those tasteful bronze numbers on driftwood, the wrought-iron script, the kid-painted mailbox---they're all damn near invisible from the driver's seat at 2AM.
It's simple: if you can't easily read your house number from the road at night, you should do something better.
What we like are big(3" minimum) reflective numbers, as close to the road as possible, facing both directions. It's even better if you add a set next to the garage door so that when we pull into the driveway we know we've got the right house.
Also: Turning on all the lights is a big help if the call is at night. And have someone stay on the phone with the 911 dispatcher if you can -- they can relay information to the folks who are responding while they are talking to you.
Thanks!
