My laptop didn't get owned...
Last time I went I just had a fresh install of Slackware on my laptop, and I didn't even try very hard not to get owned...
This year though, I'll be tunneling all my traffic, including DNS to the VPN that I run on my desktop at work, after hopping through a university Linux server. I've heard stories that people ssh to a computer, someone sniffs the destination address, and owns that box, so I plan to only expose attack surface that I don't own...
Should be good fun, except I hear that the weather is supposed to be interesting. 101 Degrees F during massive thunder/rain storms. I'd bet good money that it won't just be a dry heat any more.
Best get myself to sleep so I'm fresh for the road trip tomorrow.
