"In downtown Bozeman, Mont., the flashing blue light set atop the old Bozeman Hotel has long been a beacon for alpine skiers."
Christian Science Monitor
Actually, it's the Hotel Baxter and it is no longer a hotel. The sign violates city law, but has been given a variance: "pursuant to Title 18, Chapter 52, Section 160 of the Bozeman Municipal Code the Baxter Hotel's 'Hotel Baxter' roof sign, including the blue light ... having historical significance ... may lawfully not conform to the provisions of the Bozeman Municipal Code."
Only one other beloved sign has been granted such an exception.
