Nevada’s tourism and gambling industry has come roaring back after the pandemic shuttered casinos and kept tourists away last year, with casinos setting a record in May by winning $1.23 billion. It’s the highest single-month win in the state’s history, blowing past a $1.165 billion record set in October 2007. The record win came before tourist-reliant Nevada on June 1 lifted virtually all restrictions on crowds and business capacity statewide.
