When I took off this morning the Altimeter was 30.45 or there abouts. As
the day progressed it rose and rose and rose. By this evening it had
topped 30.60

That's just 'cause you operate in that balmy DCA climate :-). I am betting
that Jay's neck of the woods has seen greater that 30.90 in the winter time.

Its hard to pin down what the all time record is, but somewhere in Siberia
claims a 31.60 in 2001.

According to: [see, clearly credited, and in advance!!!] :)
http://en.wikipedia.org/wiki/Barometric_pressure

"The highest recorded atmospheric pressure, 108.6 kPa (1086 mbar
or 32.06 inches of mercury), occurred at Tosontsengel, Mongolia,
19 December 2001."

But is that altimeter setting or atmospheric pressure? The altimeter
setting is the atmospheric pressure extrapolated to sea level. If
Tosontsengel is above sea level, then the altimeter setting would have
been higher than 32.06.

BTW, in the U.S. you can't fly when the altimeter setting is above
31.00 (FAR 91.144)

It doesn't say you cannot fly, it just says you cannot "operate an aircraft or initiate a flight contrary to the
requirements established by the Administrator and published in a Notice to Airmen issued under this section." In other
words, you have to follow the NOTAMS and other special instructions...

Sure you can. You just have to comply with the NOTAM which would be issued.
