Bikers will generally not bother anyone, and they will almost always help another biker who is by the side of the road.
There is a big difference between bikers and members of motorcycle gangs.
I am a 55 year old guy who rode across the country last summer. It was the best ride of my life. I met wonderful people, and saw great things. Saw a bunch of biker gang folks out west. None of them were the least bit interested by an old guy on a big dirt bike.
Abilene Police say Lewis is the President of the Abilene chapter of the Bandidos Motorcycle Club, and was involved in the stabbings of two members of the Cossacks Motorcycle Club, based in Callahan County. The victims suffered non-life-threatening injuries in the altercation outside the busy South Abilene restaurant.
