It looks like those guys that saw us playing Ultimate on Whitnall the other night were right.

Ramsey on protests: 'So far, so good.'
"Despite concerns there might be raucous confrontations outside the World Bank, there were no altercations along the metal barricades erected in front of the building. Instead, protesters wrote in chalk on the asphalt, tossed Frisbees, held signs urging "people over profits" and engaged in street theater using giant puppets and staging a skit ridiculing American foreign policy in Colombia."

Making the logical step that anti-globalization protesters are today's hippies (both represented the leftist cause in their time), we see that hippies do in fact play frisbee.
