While Hippie Hill was crowded with revelers and getting trashed, Dolores Park was a haven for more laid-back cannabis consumers yesterday. It looked like it does on any other afternoon when Mission Local rolled up, but as the nominal hour approached, the park did fill with people and puffs of smoke. At 4:20 sharp, a cheer went up. Wafels were eaten, cannabis patterns were worn, herb was smoked, and a few people were interviewed about it all.
