Thanks Zack and Jim!

Yes indeed, so far my Garmin Vista HCx hasn't had trouble finding a
signal in tree cover, so I'm pretty hopefull it will show the exact
boundary plus error for my photographs and site video.

I'm also finalizing plans for the operation with ARRL HQ VUCC group --
I want to be absolutely sure all the I's are dotted and the T's are
crossed prior to heading out.  It's not going to be an easy
expedition, so it will be good to have everything possible cleared
beforehand so there are no questions later!
