Then there's the large farm animal in the seat in front that decides
to dump their seat back into your kneecaps when you're working on
dinner or the laptop.

Fortunately, I think the airlines have reduced the recline of the seats so
that it only goes back about an inch...

I checked on http://www.acela.com and the Boston to DC Express run
is around 6.5 hours for a little over $200. And it's only that long
due to the fact that they can't sustain 150mph the whole way. Of
course there are stops along the way, but the main impediment is track

They go 150mph for a surprisingly short amount of time. I believe it's
through the south end of Rhode Island, and lasts about 15 minutes. I
haven't done that ride in a while, but that's about what it used to be.

Just curious, how long does it nominally take the little guys (say a
Piper or something that can make it w/o having to re-fuel) to get from
BOS to DCA, assuming weather isn't an issue?

From BOS to DCA is about 350nm. In an Archer @ ~115kts, that would be just
over 3 hours. However, a direct flight would take you through NYC and
Philly airspace, which could add time. Wind is also a factor.

In a Bonanza @~ 170kts you'll save almost an hour and arrive in just over 2
hours.

I wouldn't land BOS or DCA in an Archer or a Bo, though. I don't think
Logan is very GA friendly, and there are airports nearby to choose from
that are much more GA friendly (I used to land OWD quite a bit a few years
back). DCA is very restricted since 9/11. I don't think GA aircraft are
allowed to land there at all anymore, and pilots need special clearance in
order to land at any of the three nearest public airports. I think the
nearest usable airport now is probably Freeway in Bowie, and it has a
fairly short runway, though...
