It’s a sound you instantly recognize, and one you hope isn’t coming to your location. It’s the wailing siren of an ambulance responding to an emergency. In the National Park System during the height of summer, the sound can be very familiar.

In this week’s show, we sit down with a paramedic who triggers the siren when he jumps into his ambulance in response to a call for help. It’s a conversation that will leave you with a better understanding and appreciation for the vital role these individuals serve in seeing that national park visitors who are injured or come down with a debilitating illness receive prompt care and are able, if possible, to resume their vacation.
