Are you proficient at sign language? If so, how did you first become interested in learning it? ~

As a rail yard switch man we used hand signals to relay instructions to the hoghead (engineman) before they allowed use of radios. 

There's only one hand signal I need to know.

I don't have enough deaf people around me to make that worth-while.

In Arizona there is always a sign on the curve that goes from one freeway to another. It is always yellow and it always says "45". Most people don't know that yellow signs are advisory. They assume it is a speed limit, and then they get on the freeway still going 45 MPH. Honking at them has no particular effect, except that they might honk back. And if you complain to any official person, the response is always "What, you think it should be higher than that?"
