In rural Alaska, providing health care means overcoming a lot of hurdles.
Fickle weather that can leave patients stranded, for one.
Also: complicated geography. Many Alaskan villages have no roads connecting them with hospitals or specialists, so people depend on local clinics and a cadre of devoted primary care doctors.
I followed one young family physician, Dr. Adam McMahan, on his regular weekly visit to the clinic in the village of Klukwan.
