Occams Razor

Since this is a more modern setting, are we allowed modern tech devices? Cell phones, mp3 players, or pocket game consoles? Can the military types use walkie-talkies with head sets if they stay off the staff channels?

Obviously a cell phone shouldn't be used in an OOG fashion, but I could see a character trapped in a warehouse or being chased through the woods calling a friend for help. Same goes with walkie-talkies. They've been pretty successfully used as an in game element over at Future Imperfect for years. (Catching random troop chatter from enemies has always been fun.)

I believe there's been some discussion about this and from what I remember the answer was yes. But I'm not plot and can't give you the real answer on that.

So wouldn't a player to player walking talkie system be closed as opposed to being linked into an outside CB network or something?

Now this does bring up questions that I had planned on waiting on.....but since it's already been broached.

I can understand the no communications, That's cool.

Flashlights? Tromping around in the woods is such a pain with just a glowstick. Plus it's so atmosphereic to catch a glimpse of the monster in a flashlight beam

MP-3 Players? Some of them can receive FM radio, but most are just so you can have your theme music playing as you sneak through the woods (And what monster doesn't love sneaking up to someone oblivious wearing earbuds)

Tablet or Laptop? (Not for walking around in the woods. You'd have to be crazy to risk it getting dropped/smacked. But more for note taking, typing up a journal story and Angry Birds back at the cabins)

Door beeper? My first thought when i heard it was a Modern day LARP with cabins was to bring one of those travel alarm door hangers that goes off like an alarm clock when the door handle is turned/opened. But then I saw the Nochian Sign and Security System qualities and went "Oops!"
Hiker's GPS system? Mostly to keep people from getting lost in the woods.

Binoculars? Spot the Bluebird, spot the Mi-Go, run like crazy

I would also suggest the banning of two items.
Cameras should be ok, but No Flash photography at night. It would be dangerous for NPCs to get blinded
Two, no bluetooth connected items. Should be covered under the same Interference preventing the communications. So no bluetooth video cameras planted along the trail or the back of the cabin

And of course, this is all with the understanding that you don't bring anything you don't want to see lost/broken. Because that happens at LARPS and you only have yourself to blame if it does

At Lost Eidolons we were allowed flashlights, but only if the beam was covered.

If you're willing to invest that kind of effort, why not pay someone small, fast and willing to die to run for you? Think of it as the movie "The Transporter" except the main guy isn't so bad ass. Pay a fee depending on the task, half now, half if they don't get devoured by the evil that's trying to kill us. BONUS POINTS: send a message to an enemy of "I brought you some friends" pay the guy, and hope he makes it
