I tried listening to that teleseminar but could not get it to
play? Don't know why?

Heard on the news this morning that some hunter was lost in a forest somewhere. A recue team told him to stay put; they knew where to locate him. And I'm thinking, this is a great advantage to all the new technology! If it can save lives, it's huge!!!!
