Unexpected overnight guest

We were trying to get the kids to bed tonight and they were keeping up their normal chattering and bantering back and forth.  They kept mentioning a car on the road and kept talking about a light down the road and did we think we should check it out. (The weather is horrible tonight and there is no way to even get out the driveway - way below zero wind chill, winds and blowing snow) I was intent on getting them to bed and kept saying I would check it out in a little bit.  Finally, one of them said, "Mom, will that person die tonight if they are stuck?" I looked out the window, and sure enough, there were headlights about 1/2 mile from our house - and they weren't moving.  So we made some phone calls - to the sheriff's office - they wouldn't be able to get anyone out.  Snowplows had been called back - all the roads in the whole surrounding area are closed down.  We tried calling someone nearby who we knew had a snowplow on their pick up truck - no luck.  Finally we got a phone call from someone he (the person who was stuck) had called who knows us asking if he could come here.  So he walked - and thankfully he made it.  It is still amazing to me how intertwined this small town/country life is.  Somehow everyone knows everyone through someone.
