What is to keep concealed carriers from drinking? I'm glad you have an unwavering faith in your fellow permit holders but everyone tries to "push the limits" now and again and you will have people who carry weapons drinking. Because never has a normally law abiding citizen drank too much or drove or anything like that.
I'm going to be honest with you that behind actual criminals with guns, people whose paranoia has brought them to the point were they feel they need to carry don't sit well with me.
"According to Tennessee code, riding in the center of the right lane is incorrect. "
Actually, it says: "ride as close as practicable to the right-hand curb or edge". Given the roadside detritus and visibility issues the center or close to it is best for the bike. What would stand up in court would be your argument, like a "too fast for conditions" violation.
