I just got an email from a friend of mine regarding a solo cyclist on SGRT that got mugged. It happened just outside of El Dorado Park. Two hoodlums knocked this solo cyclist off his bike, stole his wallet, his cell phone, and his bike. They also broke his nose. My friend's friend, rode through there about 30 minutes after it happened.
I have always had issues with riding the river trail alone, and this further supports my fear. I will not ride the river trail alone. So if you do decide to ride the river trail, try to buddy up with someone. The river trail is so isolated, that if someone decides to attack, no one would ever hear about it. And this is not the first time I've heard of this happening. The previous times I've heard this happen are usually on the weekdays.
