Police issue zero tickets during annual marijuana celebration

I think it's funny that being a pot-head for more than 30 years, I never gave much significance to 4:20. I won't bother to go into the "legend" of 4:20, but this weekend was, of course, 4/20, and apparently every year there are gatherings (some who even wait until 4:20 p.m. -- not a.m.) that light up in public and get high.

"Nine, eight, seven ..."

A crowd of about 10,000 people collectively began counting down on the University of Colorado's Norlin Quadrangle just before 4:20 p.m. Sunday.

Yet the massive puff of pot smoke that hovers over CU's Boulder campus every April 20 -- the date of an annual, internationally recognized celebration of marijuana -- began rising over the sea of heads earlier than normal this year.
