Newfag here. I live in rural Texas, a few miles away from town, and want to start riding a bicycle to town. Maybe I'm just a coward, but any advice to stay safe? Most of it looks like picrel and the speed limit for cars is 70mph for most of it. There's a few miles where there are no backroads to avoid this. Is it safe to ride on the shoulder? I have a helmet and a high vis vest, is that enough?
