50 Silberlinge

University of Colorado police have posted 150 photos of people attending an annual gathering last week where hundreds smoked marijuana. Police are offering $50 rewards for information about the people, many of whom are shown with hand-rolled cigarettes, glass pipes or bongs. ... Authorities said the protesters they were trespassing on Farrand Field, which is surrounded by several dorms, despite signs and security posted to keep them away. About 2,500 people attended the festive event, but police estimated less than half were using the drug.
