My mom was really into crossword puzzles, but they aren’t my favorite. For a long road trip, I used to buy one of those variety puzzle books, that had all sorts of puzzles including a few easy to moderate crosswords. I have trouble doing puzzles in the car for long periods though, as it tends to make me motion sick. I think we did Mad Libs in the car on road trips more than puzzles, but I liked something to do in the hotels on the road in the days before internet and entire libraries on an e-reader. Now I just take my iPad.
