I have read/heard about a nice fish aqurium I believe in the Silverton Casino, is it true? Also I thought I heard somewhere where the tank had mermaids and such every so often performing? Basically I am looking at what non strip and downtown things to do on my trip out this time. Outside of GVR and Sams Town I have not been to any other non strip/downtown hotel/casinos and thought about checking some out this trip. Any suggestions?
