I just love stuff like this

The PocketMod is a little eight-page booklet for you to customize, print and fold. I just made one for my up-coming San Antonio trip that includes my emergency contact information, flight schedules, hotel name and number, plus a couple of lined pages for taking notes, a couple of pages of check book register to keep track of my finances, and a sudoku game. The software isn't without its glitches just yet; the text I entered into the blank custom page showed up on screen but didn't print and I had to use a work-around. Still, I'm going to keep a close eye on it; it's useful as can be. I'd recommend using CutePDF to print to a file so you can double check your print-out before wasting paper.
