But I would have to question your statement: "Milwaukee's varies with
runway
usage. Sometimes it's along runway 7/25, sometimes it's along runway
1/19".

How often would a pilot know the active runway prior to calling
Approach?

Seattle has a similar situation. Before calling Approach, you listen to
the
ATIS, because the sector divisions (some of them) depend on which
direction
the traffic is flowing.

They're not secret. They're just incomprehensible.

Nearby Boeing Field has the same flow-dependent sector boundaries as SeaTac
(http://www.airnav.com/airport/KBFI), and like the OP there is no stated
point on which they are based. If you need to be accurate, assume the SEA
VOR. Don't try asking Boeing Tower which frequency to use for flight
following either; at least while I was based there, they usually couldn't
figure it out.

I much prefer it up at Everett, where approach and departure is handled by
one Center frequency (yes! a Center controller lining up spam-cans for one
of 5 different approaches).
