Since a pilot can get a Special VFR clearance pretty much anywhere that
there *isn't* Class G airspace near the surface (generally below 700 or 1200
feet, depending), this means that as long as the helicopter pilot can see
well enough to avoid obstacles, the visibility is defined as being
sufficient, no matter how low it actually is.

It was my understanding, that a Special VFR clearance was only issued
within the controlled airspace of the surface area of an airport:


§ 91.157 Special VFR weather minimums.

(a) Except as provided in appendix D, section 3, of this part,
special VFR operations may be conducted under the weather minimums
and requirements of this section, instead of those contained in
§91.155, below 10,000 feet MSL within the airspace contained by
the upward extension of the lateral boundaries of the controlled
airspace designated to the surface for an airport.

That doesn't seem to be what you are saying above. Did I miss
something?
