After I've finished the New Model Army in Grand Theft Auto San Andreas, where do I go next?

Blue "SKULL" Icon under/near the Ganton Bridge for Jizzy's Pleasure Palace.

"W" icon north of Doherty garage for Woozie's Betting Shop

"C" or "CV" icons on the Doherty garage for Carl's or Cesar's mission.

You did not say what required mission(s) you have completed, as Zero's were optional.

Here is the Mission Tree that should give you a clue as to what should be next: http://en.wikigta.org/wiki/Mission_tree_...

If you have not already found Katy (nurse who will allow you keep weapons when "Wasted") she is on the golf course rough directly south of the SF Do Jo. (Gym).

There are 50 Photo ops to collect:

Collect all 50 Oysters, and the Girlfriends will love CJ regardless of how he looks (fat/skinny/normal)
