5 Awesome Spots for Epic Rooftop Pools in Billings The extraordinarily hot summer we are experiencing is becoming more and more difficult to chalk up as "just a hot year." I've lived in Montana for most of my life and I've never seen a 114 degree reading on my car thermometer. For that matter, I've don't recall ever witnessing the reported high of 106 at Billings Logan International Airport. But this story isn't really about climate change. It's about something much more awesome... rooftop pools. Like the ones you'll find at fancy hotels in big cities. Or, at the lavish new Kimpton Armory Hotel in Bozeman. I believe it's the only hotel in Montana with a rooftop pool.
