My son left a couple of days ago on a bike trip to visit relatives 90 miles away. I inspired him to get into cycling in the first place. He's better at it than I am. We've done overnight bike tours together. He's got good lights and all the safety equipment. And yet, and yet ... I still worry about him. Sorry guys, parents are just that way and nothing's going to change it.
Maybe cycling parents can be even worse because they know how bad it can get out there sometimes.
