Logic puzzles

[Astra]

I'm going to be spending a few hours on a plane this week and picked up a book of logic puzzles. I've been addicted to them since grade school. Anyway, I just found a really cool site where you can work them online, with the charts and everything. Just click "play" to bring up the puzzle of your choice: http://www.puzzles.com/projects/LogicProblems.html

Yeah, I'm a nerd :smt118
