In early June, Donna Bilgore Robins stood on a patio in Beaver Creek, Colo., under a crystal-clear blue sky and tried to catch her breath.
She couldn't.
With mountain vistas around her, Robins felt as if she was drowning. She gasped for air hungrily again and again.
Robins knew all too well what was happening. Something -- some kind of plant? something in the mountain air? -- had triggered her asthma, a lifelong condition.
She also knew she was in danger, even with a rescue inhaler at hand. "I don't slowly get sick -- I just drop," said Robins, who with help from her husband was soon on the road to seek medical attention over 100 miles away at National Jewish Health in Denver, a leading hospital for people with respiratory conditions.
