Chicago - With its acquisition of Coast Casinos closing Thursday morning, Boyd Gaming will climb another big link up the casino industry food chain. The combination, overshadowed in recent weeks by the pending blockbuster merger of MGM Mirage (MGG) and Mandalay Resort Group (MBG), will not only make Boyd (BYD) the fifth-largest gambling company but also secure its place among the red-hot Las Vegas locals market while giving it a near 50/50 revenue split between Nevada and other states.
