On another site I posted some suggestions for married men to protect their anonymity and gaurd against blackmail. A couple of those recommendations are to get a Postal Annex type mail box and use it (1) to get a Califonia ID card, and (2) a seperate bank account. Those afraid of blackmail might also use it to register their car. You can also get a prepaid credit card at many check cashing places. The usage fees are high and they are tricky to use in TJ, but they are better than letting a wife see withdrawals made in TJ.
