Actually I was with a team. A whole strike team was with me where I was allowed to set up, and they had radios. Actually when I walked off to take a leak, I had a loaned FD HT (radio) and my fire shelter with me (which I can deploy in less than 30 sec which is a FD standard drill). I wasn't in a ravine, LOL, I wouldn't place myself there, nor was I in a chimney. That is a "ravine" that runs steeply up the side of a hill or mountain for those who want to know.
Yeah, I know how to position myself. And the 70 mph thing, you better believe it, I have the footage to prove it, because I saw it last night. Yep mid slope situations are bad (that's how the crew from USFS was killed a few years back on the Banning Pass fire). I was on a bench with the wind to my back, fire advancing against the wind. The bench was clear of all brush and a defensible space for about 300 feet all around us. So there really weren't any rules broken here. The BC and the PIO knew I was with the crew (and therefore the command structure) and were fine with it. They also knew that if the proverbial sh@t hit the fan, I could handle an 1 1/4" crosslay off one of the rigs.
Basically, the point I was getting to is good luck getting permission to access a fire scene, unless you are with an agency, or can prove your training to the powers that be on a scene. The other point was, yeah, it is F'ing dangerous and you better be prepared to accept the tremendous risks if you do cross without permission.
Hanging around a bunch of Firefighters doens't make you part of their team. It makes you a journalist standing around a bunch of firefighters. Any BC that would consider you "Part of his crew" should be relieved of his command for gross imcompetence. Ditto for loaning you a radio. You should either be a filmmaker or fireman. No such thing as fireman-filmmaker.
Also, I wouldn't get too comfortable with that fire shelter, they're easy to deploy in a drill, but try it with an 80 knot wind blowing and a 200' high flame front heading at you like a freight train. It's really your last move before sticking your head between your legs and kissing your butt goodbye. For anyone that doesn't know, fireshelter is a piece foil shaped like an old pup tent, when all else fails you pull it out and ruffle out and climb under it. And there's some stuff about scratching out a little breathing pocket in the dirt. Then you wait for hell's inferno to pass you by. There's a red button on them that pops out when you are properly cooked, kinda like a turkey.
