Caseless I understand completely we go through the same thing here every year. I prefer to hunt alone and i usually laugh when my wife asks where i'm gonna be, cause I may end up 20 miles from where i started from.
I have been looking into some of the Garmin rhino's from what I understand I should be able to leave one at home and take the other with me, as long as its getting satelite reception my family will know where i'm at.

Good luck
