We are slowly working on the mobile command post idea, but at the moment 
the $$ isn't there (and probably won't be for a couple years). Right now 
we are using borrowed equipment which is why the trailer may not always 
be available.

I'm hoping for a uTNC for Christmas to play with :-) We will probably 
end up putting a small tracker/digi in the radio box also just in case 
it grows legs (if we have to leave it somewhere for whatever reason). 
The uTNC seems like a good choice for this. We have a second D700 
dedicated to being a digi, but given the terrain and vast search areas 
we sometimes have one isn't always going to be enough.

No, we aren't. We are ground pounders, and don't normally go above the 
treeline. We used to be Explorers but have slowly gotten away from that 
name, although the majority of our 70+ members are teenagers.
