If you want to make the quick walk off-strip to Silver Seven's between 4PM-1AM, you can hop into the 2/4L game and try to snag a few decent condition $1's. Somebody would surely insta-buy them on the classifieds.
Call me picky but there really isn't any chip I love on the strip right now, maybe Paris. Mostly due to a lack of THC and RHC chips.
