NEW BUFFALO, Mich. The expansion of the nations casino industry, which has been a boon to the motorcoach industry for the past 15 years, seemingly continues unabated. A few of the latest examples:

After six years of legal wrangling, the $400 million Four Winds Casino Resort, southwestern Michigan's first casino, opened last month. The Pokagon Band of Potawatomi Indians owns the complex on a 675-acre site off Interstate 94 at Michigan Exit 1 in New Buffalo.

The casino has 130,000 square feet of gaming space, including 3,000 slot machines and 100 table games. It also features a 165-room suites hotel, six restaurants, entertainment bars and retail shops.

In late January, Harrah's Entertainment opened a 2,750-slot casino, called Harrah's Chester Casino & Racetrack, southwest of Philadelphia.

Harrah's Chester has 100,000 square feet of gambling space, plus the usual assortment of restaurants and bars, plus daily simulcast video of horseracing.

In July, harness racing returned to the adjoining track; the racing continues through much of December.

In February, Presque Isle Downs opened in Erie, Pa. The racetrack and casino is situated on 272 acres just south of the city off Interstate 90.

The casino is up and running and the racetrack is expected to open early this fall.

Presque Isle Downs has more than 2,000 slot machines, plus two restaurants, two named bars and a buffet.

In May, Harrah's and entertainer Jimmy Buffett announced plans for a new Gulf Coast gambling palace, Margaritaville Casino & Resort, on the shores of Biloxi. The project investment is expected to be $704 million.

At the news conference announcing the casino, Buffett performed a couple of songs. Whoopee.

In Middleborough, Mass., voters overwhelmingly endorsed a deal with the Mashpee Wampanoag Indian tribe that could bring casino gambling to the Bay State for the first time.

The town residents gathered at a community meeting and voted 2,387 to 1,335 in favor of the tribe's proposed $1 billion casino. Middleborough has a population of about 20,000.

In exchange for allowing the casino, the town would receive $250 million in infrastructure improvements and an estimated $11 million in annual payments, among other benefits.

Significant hurdles remain, however. The tribe, which officially received federal recognition in May after more than three decades of fighting for it, still needs state and federal approval for the casino.

The vote came after about 2.5 hours of debate on an athletic field behind the high school. Residents sat in lawn chairs under umbrellas and ate food they brought with them.

Meanwhile, another Massachusetts tribe, the Wampanoag of Marthas Vineyard, could wind up with the state's first casino-resort.

A local developer, who is pitching plans to build a mega-casino in the western Massachusetts town of Palmer, says he has had preliminary discussions with the tribe about teaming up.

The developer apparently wants to involve the tribe in the project because casinos run or owned by Native American tribes generate higher public approval ratings - a factor in the politically charged gambling issue.
