The worst class trip ever - Dave Barry

In this hilarious misadventure from Pulitzer Prize-winning humorist Dave Barry, a middle schooler and his friends try to save the president when their class trip goes off the rails.

Eighth grader Wyatt Palmer's primary goal on the class trip to Washington, D.C. is to avoid embarrassment in front of his dream girl, Suzana. That dream is crushed before they even get off the plane, when his best friend Matt notices two rather suspicious men seated behind them
and decides to steal their mysterious luggage.

What do you get when you combine a bunch of hormonal thirteen-year-old boys and a perceived threat against the White House? You get in trouble-not just with the teachers, who are losing patience, but with the mysterious men from Row 11.

In this funny, fast-paced adventure in the nation's capital, Wyatt and his friends, including a fearless Suzana, try to stay out of danger (and out of the doghouse) while chasing down an enormous threat to national security
or so they think.
