Bob,
I enjoyed participating in the 2013 experiment and would like to be a part of this event as well.  I still have my D72, but also have a Thd7 as well as a ft-350 mobile in my vehicle.  I also have an RV with a dual band mobile (no tnc, but could use sound card and software to receive) that could be used as a command center.

I recently spent a day in the historic cave volunteering doing cave trail maintenance and it was nice to see the weather stations set up in the cave monitoring conditions, so this work does have very practical usage. I have a couple of good contacts with the park if you need help scheduling or coordinating.

Please add me to you list of interested participants.
