On Saturdays from May until September, Hines Park closes Hines Drive from 8 AM to 3:30 PM so that people can ride bicycles, walk and rollerblade in the road and not have to fear traffic.
They close the road from Outer Drive and Hines Drive (near Ann Arbor Trail in Dearborn) all the way to Hines Drive and Ann Arbor Trail (where they cross is about 12+ miles away? 7 miles?). Many of the parks along that route are open, you just need to access them from a road other than Hines Drive. The parks are the two ends are semi-barricaded off, but it does say you are allowed to drive around them at Outer Drive to get to Helms Haven Park and at Ann Arbor Trail to get to Nankin Mills Park.
The video has a bit of the Rouge River and some geese and baby geese (goslings?). At the end it was later and the road was open, but all the times I shot video, I think I’m on the sidewalk.
Video and photosynth both shot, edited and uploaded from my iPhone 4s. It’s not very fancy edited, just put a few clips together (trimmed a few) and added a (tiny) bit of text.
