Brother Willie..
Did Dave give you any indication when he might contact the rest of the world? When you left him, did he seem capable of getting out of there? Those stones are very painful and pretty incapacitiating. If his battery was dead or something, wonder if he'd have had enuf stamina to take care of things without any help.
What was your opinion when you left? Know you had to get home, but were you comfortable with leaving him?
Like Tom, am getting very concerned..sort of hope someone on here knows more.
