Check out this jaw-dropping video of four remarkable athletes who turn Durham, Raleigh and Chapel Hill locations into their personal Jackie Chan playground. [2/24/12 update: See Road Worrier column.]

What are they promoting?  Public transit.  This is Try Transit Week (bus rides are free today, Thursday). The "#flipfortransit" video was posted by GoTriangle, a  marketing arm for transit agencies in Wake, Durham and Orange counties. (Find this and other bus-riding videos, including one with cute preschoolers, at youtube.com/gotriangle.)

And when they get back on the bus, they're not even breathing hard.

Here are the credits:

I didn't know what parkour is, or what freerunning is. Now I know.
