Interesting...

I am not back, as there are only a few who actually read this, just felt compelled to comment.  Not counting all of the Russians and others...

I grew up in a time that there was no 9-1-1.  If you had an emergency, you called a 7 digit number, or if it was really an "urgent" emergency you dialed "0" for the operator and asked to be connected.  Now everything is a 10 digit number, unless it is a 3 digit emergency call.  And now there is the 4-1-1, 5-1-1, and I think the 2-1-1 system in the US.

Just a Hmmmm...
