Yea, I used directions from the NASM website to get there, seemed to
be enough signs, maybe theyve been put up since Jim's visit. As far as
the people working there, yea the security guards doing the whole
metal detector routine at the front dont seem to be all that great
(they didnt ask you to take the metal out of your pockets, so it went
off for everyone going through, and they didnt bother to stop anyone,
except for bag checks), but there is a Welcome desk just beyond the
entrance that seemed to be staffed with capable people.
As far as the up and down stuff goes, yea that can be a pain, but
after spending the previous two days walking and walking and walking
around the city, I was used to it.
