Well, I think it's silly *now*.  Maybe I'm terribly wealthy or
something, but really, a couple cents is down in the noise.
I think I misplace more money that that every month.

And when does 1+ toll alerting kick in?  Zone 3? beyond Zone 3?
inter-LATA?

My telephonic memory starts around 1976, at that point,
we had just been cut over to a 1A.  The CO also had
step and xbar, but I was lucky.

Fortunately, MarkTel doesn't fall under the jurisdiction of the CPUC :)

Yeah, and going to 1000 block number assignments helped provide
relief for 310 as well.  The overlay for it was originally scheduled
for 1999.

I'm a huge proponent of overlays, particularly in urban areas.
The phone number my parents had since 1968 was recently assigned
to a law firm downtown.  :(

Yeah, I had to train my customers (my parents and a couple of friends)
to use 10D on all calls.  It took them a while to give up the 1+ habit,
but eventually they got used to and liked it.

My cellphone is in 310, so 10D or 11D is required on all calls

I have numbers in my cellphone's phone book programmed as
"+1 NPA NXX XXXX" so that when I travel internationally,
it just works.
