A group of dirt bikes and ATVs were seen riding on sidewalks and running a red light this weekend in downtown Denver. Neighbor TJ Jeffrey captured a video around 1 a.m. Saturday near 17th and Glenarm while walking his dog, Chapo. “I’ve lived downtown for 15 years, and nothing surprises me, but I hear it all the time,” Jeffrey said. “It’s just crazy. The safety for themselves too, like no one was wearing helmets.”
