Dennis,
Just have him walk up to the cage at any Casino he is in & ask at the cage. Have him ask for any LE's that have not been on the tables. He will find some LE's for sure Downtown at:

Four Queens
Las Vegas Club
Horseshoe
El Cortez

On the strip:

Tropicana
Stratosphere

Just off the strip & within walking distance of each other:

Palms
Rio
Gold Coast

On Rancho:
