Actually found a 3:2 Blackjack table here
I was astounded! After finding only 6:5 at my beloved Mirage and all other mid-level places I checked, I found a 3:2 table at the Margaritaville Casino of all places. It was towards the back and to the right. Not even crowded; no one there seemed to know the difference. BTW: 3:2 means the dealer pays you 1.5 times your bet if you get blackjack. Most casinos are moving to $6 for every $5 you bet, which makes a huge difference in the long run.
