Triangle Explorer (thanks!) reminded me that the RTP will have a Food Truck Rodeo this Thursday, March 20th at their Headquarters on 12 Davis Drive.

The lineup for this rodeo is: Pie Pushers, Only Burger, Chirba Chriba, MaMa Dukes, and The Parlour. Awesome line-up, maybe I can take a power lunch that day.
After March 20th, Rodeos will be every Friday starting March 28th and located at 800 Park Offices Drive (which is on the opposite side of I-40 closer to NC 147).
For more info, read the RTP blog.
