My wife and I are on a canoe expedition floating in the Missouri River from Montana to St. Louis, a distance of over 2300 miles. About 1500 miles along the route, we stopped to establish camp 75 on shore. As the weather forecast predicted strong storms and hail I opted to locate a campsite under a tree to afford protection from hail as we sleep in a tent. Unfortunately a snake was also under the tree that I was scoping for a tent site, and it bit my left leg. I immediately knew I was in mortal danger, remained calm and activated the rescue beacon as well as contacting 911. Within minutes shock was overcoming me. My wife cared for me till a rescue boat and personnel arrived about 45 minutes after the snakebite. After boat transport to a boat ramp, I was taken by ambulance to a nearby hospital where I received snake anti-venom and then was air transported to a regional medical facility spending two nights in ICU and two more nights as inpatient before discharge. In a remote location and no ready options to get to medical care, the ACR rescue beacon, and the local first responders that rescued me, saved my life. We are awaiting a new beacon and my recovery before resuming our epic journey.
