House of Air, the trampoline park in the Presidio that we wrote about recently, found time in between 911 calls to host a team of professional parkour jumpers recently. In parkour, gymnasts make their way around streetscapes in an acrobatic manner.

HOA sent out an email Thursday touting the visit. The video shows the traceurs (parkour practitioners) springing around notable San Francisco sites, including various decrepit batteries in the Presidio, the serpentine of Lombard Street, Coit Tower and the grand steps of the University of San Francisco.

As evidence that the footage was taken more than a week ago, the stunts were performed on a bright, sunny San Francisco day:

House of Air posted a separate video of parkour jumping at their facility. The video carries a large disclaimer: "Watch the PRO's [sic] take care of business in our park. Ryan Doyle and Brian Orosco and the Red Bull Team tear it up. Remember these are Pro's - don't attempt these tricks."
