I'm with you on all of this PW. I usually ride with a group but sometimes I have my own schedule, my own goals, or just a desire for some solitude and will ride alone. Right now, I'm not sure that's such a good idea and, like you, I hate that I feel like I have to ride with someone else just to feel safe. I was planning to do a solo ride this Sunday (not on the Silver Comet). Until today, I wouldn't have thought twice about it. Now, I wonder if I should change my plans.
It's incredibly sad and I feel so bad for her family.
