I decided to do some research, however and found this site detailing where lice come from.
"Long before recorded history, head lice were living on human beings. Except for occasional strays to close pets, head lice are found almost exclusively on humans. Birds and other mammals (both wild and domestic) have their own lice, but those kinds cause only incidental problems for man. Anyone can get head lice, but they are most often found on young school age children."
And thus my conclusion is that it's virtually impossible to get head lice from going camping, unless one of your friends passes it to you.
Just thought I'd post this in case anyone was harboring this irrational fear also.
I "dread" the day I would have to remove lice from my hair.
har har har.
