2010 I had my own experience riding alone. Trail riding I had the front wheel kick out to the side and sending me down hard on the right side. Ended up with a spiral fracture of the Tib/Fib on right leg.
Fortunately I was still in cell coverage and was able to call for help.
After that I prepared myself better with a SPOT, First Aid kit, Emergency blanket, tools, water, food and a big can of bear spray. (might slow em down a bit)
I almost always ride alone and ride with more caution then when I'm with others.
On two wheels....That's my Happy Place!
