The only anxiety I have is forgetting to bring something important. And it’s happened. On my last trip, I forgot my headlight, but it worked out OK. I had a taillight and it was just light enough after sunset to make it to my destination. One trip I forgot to bring coffee. That was almost a disaster. On another, canceled at the last minute due to 100F temps, I realized I hadn’t packed my sleeping pad. Don’t know what I would have done, because sleeping on the hard ground was not an option. I suppose getting hit by a car is possible, but pretty unlikely, and not on my list of things to worry about. Most issues can be dealt with by planning ahead and problem solving.
