I'm sure all of the EMS/Fire/Cop people here have had many similar experiences.
Our VFD sells reflective address signs, mostly at our annual fundraiser. Not enough people buy them.
Anyway, a small but significant security and safety step you can take is to make sure that when you call the cavalry, they can find your house. (Also when you make that 911 call, tell the dispatcher your gate code.

Here's another good reason to make sure your HOUSE, not just the curb or the driveway, is CLEARLY MARKED:
Contractor Guts Wrong House
I looked at this on Google Maps, and you can see why the contractor was easily misled. The right house to be gutted was at 2700 Park Boulevard Road, and it sits on the corner. The wrong house, 2736 Forest Park Blvd, also sits on the corner, same side of the street but at the other end of the block. Painted on the curb right in front of the wrong house, in big easily read capital letters, is "2700 FOREST PARK BOULEVARD" - which is meant to designate the block, not the house. There's already a green street sign there designating the block number as well, so it would be easy to assume the curb painting is for the house.
On the house itself (which is set back from the curb quite a bit), there are much smaller dark numerals 2736 over the entryway. Both houses were unoccupied, and the contractor was told there were no keys, just kick in the front door. And he did. And took out all the sinks, plumbing, fixtures, furniture, cabinets...the works. (He as promised to make it good to the owners, even offered to buy the house from them.)
And the contractor did this in daylight, I'm guessing. Imagine if when the real 2700 was occupied and they called the po-po for an armed intruder some dark night, it would be real easy for the cops to be misled as well, with unfortunate results. Or EMS responding to a heart attack, and no one answers the door.
End of lesson. Except for "mark your house well."
