"flight" there is the word.    Why drive up a mountain?   Take the clock
with you inside the pressurized cabin of a commercial airliner next time
you are on one of those 10 hour trans=pacific flights.   You be taller then
any mountain and it is actually cheaper then a weather balloon.

Can you get a Rb clock past the TSA x-ray machine.   Maybe if you ask
first.  There must be a way to hand cary specialized equipment.
