Running up the Pit Roll 8/19

Gave myself a $300 bankroll for pit games at the casino. See how long it will last me. Just seems that at some point I'm up...at least a little. The problem is knowing when to get up. Discipline is not my forte... You have to hit and run. I was up over $100 at paigow and left a loser. That cannot happen again. Bankroll $300 Paigow -$29 Roulette +10 Blackjack +119 Bankroll $400
