Sam's Town is worth the trip. There is a great light and water show in the atrium in the evening. Plus the atrium itself is worth the trip. They are in the midst of remodeling the casino, or may be done by now. Should look pretty neat.

The flea market is out on Las Vegas Blvd North, past Poker Palace. I know it is open Sat and Sun and may be some other days as well. It is VERY large. Anything from junk to new appliances and cars, and everything inbetween. I have found chips, ashtrays, and gaming equipment on several occasions. It is a must do on every visit.
