Dallas has LNS. which was Fox4, NBC5, and CW33 with Fox and NBC sharing a chopper. A year ago when I left, it was on the verge of collapse. Not sure of the status today but LNS was a total waste of resources. Most of the time LNS crews were sent to cover breaking news that stations already had crews at. LNS footage was backup or a second camera. Even overnights was a big pain. If I'd shoot a fire, shooting, or whatever, is have 30 people on a list that I'd have to constantly update and keep informed of what's going on, with half calling me every 5 minutes wanting to know when I was feeding. This BEFORE I could even shoot a frame of video. Total pain in the a$$ and restricted me from doing my job.
LNS is suppose to be used for ribbon cuttings, ground breakings, and those press release press conferences that are :15 VO's. Unfortunately it's rarely used that way.
