What does "report her" mean? Why should the FSDO care what I say when
I
"report" a fellow pilot?

They are the ones in charge of enforcing the FARs.

Right, but it is my word against hers. Why should they believe me?

Because other people might have reported her too. If not, at least you made
a best effort instead of shrugging the whole thing off and hoping somebody
doesn't get killed by her irresponsibility next time.

Here's an anecdote. In 1990 or so, a Lake flew under the bridges in
downtown Portland, Oregon in the middle of the day, and the FAA and police
were looking all over for the guy. I saw a Lake that fit the exact
description sitting outside a hangar at TTD, having just landed, that very
day. Didn't report it, although Lake amphibs are pretty rare out here.
Should I have reported it?
