Margaret, my wife, and I were on a 2015 Lewis & Clark Cultural Tour traveling through Montana and Idaho following part of the trail of the early nineteenth century expedition. In Montana we canoed and camped on the Missouri River. In Idaho we did some strenuous hikes in order to visit Lewis and Clark trails and campsites in the Bitterroot Mountains.
After completing the Lewis & Clark Tour, Margaret and I had planned to spend a few days exploring Yellowstone National Park. We had been travelling since early morning and arrived at Yellowstone about 5:00 p.m. on July 24. After visiting Mammoth Terraces, I had a stroke in the parking lot. I remained conscious, so Margaret immediately drove me to the close by park village, where she located a ranger who called for paramedics. The lead paramedic recognized that my symptoms were very severe and immediately arranged to take me to the hospital in Bozeman, Montana, by ambulance and helicopter.
