The fliers sounded alarming: “Urgent Neighborhood Action Alert!”

They were sent to residents in North Las Vegas, urging them to attend a meeting last Thursday night to review plans by Boyd Gaming to move a proposed casino project from Lamb Boulevard and Centennial Parkway to north of the Las Vegas Beltway, just west of Losee Road.

“Join your neighbors at a community meeting to say no,” the mailings said.

But few, if any, people did.

Instead, they showed up at an elementary school in the north section of the city to ask a few questions. They were told the casino project would be on 56 acres and would eventually have 1,200 hotel rooms and a bunch of nice restaurants, like The District at Green Valley Ranch.

Residents liked that idea.

Nobody was too distressed, and the conversation turned toward who sent the anti-casino fliers, which had no return address or mention of a group in charge. Each flier was individually stamped.

Attorneys representing Boyd Gaming at the meeting refused to speculate. But there were whispers that a Las Vegas community activist could be behind the mailings.

The Boyd casino would be the second along the Beltway and part of the master-planned Park Highlands development. Station Casinos is expected to open a casino at Aliante Parkway this year.

There are five casinos planned for within two miles of the Las Vegas Beltway and Interstate 15 interchange. That area has been dubbed “Casino Alley,” a mini-Strip 10 miles north of the Strip.
