Go see the Shark Reef, at Mandalay Bay, the lions, at MGM Grand and the white tigers, at the Mirage. Catch the Fremont Street Experience, too. Slots and video poker machines, nearest the doors are looser. DO NOT eat at the Circus Circus buffet. The Rio has the best buffet.
I like to go fising at out summerhouse, but after I grew up I am sad when a catch a fish! I like more to just sit by the lake and enjoy the athmosphere, reading or writing.
