Wait til you get the win 3 hands of blackjack after hitting 3 times one.
I think the trick to that, and I could be miss-remembering, was to do it during a quest (maybe it was the tutorial?) hand. I think the first few you are guaranteed to win.
Note that I'm remembering this too from years and years ago, so I could be 100% wrong.
I learned my lesson during the Key To The City community challenge for GTAIV. Turns out once a save editor dropped, I found that one specific pigeon didn't spawn in my game. So, fuck rockstar.
You gotta pound big valley during daytime. It's the only way to do it and keep your sanity.
Oh I know All about pounding big valley
That one I 100%'ed, but I do have a bit of masochism in me.
