Vortex1 was a state-sponsored festival held at Milo Mciver state park in 1970.
This festival is a cool part of the history of Milo and OPB had a video on it last night.. you can watch it online for free here:

I look forward to hearing if any of you old farts were at Vortex and have any stories about it.
