Crushed my collar bone way out in Denali Park before the tourists arrive, just after passing by a large grizzly near the road. Took 5-6 hours of agonizing riding on dirt roads and bumpy highway to get to the hospital. My naturally low heart rate combined with my heart meds and the pain meds they gave me took my heart rate and blood pressure so low they had to stop the ambulance and contact the hospital. I have a titanium plate with half a dozen screws in it. It will be bad news if I fall on it again. It won't break nicely.
