* In Orange County, we have a place called "Little Saigon" which is located in city of Westminster.
  To get from the north, use I-5 South, I-405 South, exit Brookhurst Street (Huntington Beach) North, then left
  on Bolsa Ave. You'll be surprised to see what we have down here. Remember that this place is where almost
  one hundred thousand Vietnamese go shopping every week-end.
* Go to any Vietnamese bookstores in Little Saigon, you will find books about Vietnam BEFORE & AFTER 1975.
* Try to contact any former military friendship groups. They will help you to understand why we fought, and to
  some, we're still fighting.
* Some of the Vietnamese student groups down here also could help you further. They might speak better English
  than the older groups, like I am.
* Since you're here in Orange County, you can tune on 1480 AM or 106.3FM to listen to the Vietnamese stations.
* You can also get on www.vncr.com, www.littlesaigon.com, www.kycon.com.. to know how to listen to those stations
  on internet.
