Hey - I would never tell you to feel safe or unsafe - I mean that's a very personal choice obviously.

Still, one of the realities of living in a big city, is of course, crime. It happens every day, yet we carry on with our lives, oftentimes largely unaware. Ditto with accidents and so on.

I would ride in whatever environment/circumstance you feel comfortable with - if it is group rides only, so be it, or if you feel good solo, then go for it.
