Project Loon is looking for folks in California’s Central Valley who are willing to have a Loon Internet antenna installed on their house or small business building to help test the strength of the Loon Internet balloon connection, Google has announced on Google+.

“When  balloons fly overhead, the Loon Internet antennas will generate traffic that will load-test our service,” Google says.

Google is inviting residents of Madera, Chowchilla, Mariposa, Merced or Turlock who own a single-family home or business building with an Internet connection to participate.
