I ride regularly in the countryside of so Maryland. It's filled on weekends with Harley riders. Their motorcycles are extremely loud and owners lobby that loud pipes are necessary for safety. If that's the case why are other motorcycles quiet by comparison. They also ride in two columns hugging the center line and shoulder. They claim that's necessary to avoid road grease. Funny but Harley's are the only ones that do that. What's upsetting is when cyclists are on the shoulder they don't move and smile about how close they come.
