Greg and his family are out on a summer road trip and this installment of the series follows them on the journey and the craziness that ensues - including winning a baby pig at a fair and spending the night in less than reputable hotel.

Of the series, I have to say this is not my favorite. The story line is funny, and fans of the series will love it, but some parts are unrealistic. (And, since it takes place in the summer, I miss the "poking" school humor.)
