My grandmother...a bingo fanatic, could and would play the slots for upwards of 12-15 hours straight. Someone would watch the machine for bathroom breaks. She didn't get to the casino that often...so she made the most of those visits.
Frank, you are right about not trying to live by the casino's 24/7 schedule....in fact, it is the whole "town's" schedule too. After 3 years in Reno, dealing, playing, partying, not knowing when my watch said 12:00, whether it was noon or midnight....I finally filled up the gas tank, and headed down the road. Can I look back on it and remember everything, hell no! Can I look back on it and say, did you have fun, hell yes!
