I'm struggling to comprehend your point.
I know what the 'boonies' are. Do you really think someone in the next trailer over is going to set up camp 'in the boonies' just waiting for the opportunity to crack the OP's WEP encrypted network so he can watch some movies too?
Who does not think WEP is strong enough for the 'boonies?'
You, apparently.
BTW, I LIVE in the boonies and have an open network. Have yet to see a bear this year but I expect them to come out of hibernation soon. Saw a BIG bald eagle Saturday. Too many deer to count.
Glad you are not my neighbor...
Yes me apparently. I've done it just to prove to people how insecure their network is. Nothing drives home a point like showing your neighbor how quickly someone can hack their network. Maybe it's because I work with IT security on a daily basis, maybe it's because I'm an @$$ as well, but whatever the reason just ignoring a weak (or in your case NO) encryption because there aren't many people around doesn't mean there isn't a risk.
(I'd also like to point out Campgrounds are full of bored children just looking to get into mischief and kids these days are 100x more tech savvy than those even 20 years ago)
I also going to assume his Mac has some important data on it (personal finances, passwords to websites, etc. etc.) which once you are in someone's network it is relatively simple to track any and all computers and dump data off of them.
EDIT: By the way, why so defensive? I made no insults and simply pointed out the possibility that what you consider "boonies" may not be what the OP considers. I did not insult, but you certainly wanted to insult me.
