There was an incident in the alley between Fourth and Fifth streets and Lincoln Avenue and Yampa Street in which a guy in his 20s deliberately pulled his truck into the path of my bike, then made faces at me, then actually chased me on foot and roared at me to try and scare me. As soon as I stopped and confronted him, his bad-boy attitude suddenly disappeared. What was that all about? This isn't the first time I have seen this behavior. What's up with this "I'm bad" attitude I see among some of the younger guys these days? Especially when it all disappears as soon as someone stands up to them. What happened to respect and courtesy? What's up with randomly trying to intimidate people for no reason? I don't get it.
