Tinian is 4 by 10 miles with less than 4000 people on it. Not much night life. I guess Saipan isn't much better now since all the sweatshops shut down.
JFS, there were 3 bomber fields on Saipan, one is the current airport, one has been built over and the third is out in the boonies. I still remember going out there and being stopped by the sign saying the road was closed due to unexploded ordnance.
