Just keep in mind that in Class G, VFR is one mile visibility, and VFR
aircraft (even radioless, by the way) could be rattling around the
pattern.

That's often what we call IFR weather, and we all tend to get a bit
careless about this stuff, especially until the first time you see a
VFR aircraft land that you did not expect to be out there.

Better overkill than be killed. Not only announce, but keep an eye
out if the visibility is a mile or more.

A few months ago in IFR magazine they had a story about this. I believe
the departing aircraft was a small jet who never announced anything
on a crossing runway to landing traffic.
