You want to do what to me?

San Diego is a great outdoors city.  Everyone know about the beaches and the large park in the middle of the city, but the city also has a several canyons that criss-cross the city.  These canyons are reserved for wildlife and so cannot be built in.  They make great hiking areas.

Jen asked Matthew if he wanted to go for a hike in the canyon on Sunday.

"But Mommy, canyons kill people."

"Canyons don't kill people, what are you talking about?"

"On the pirate ships they explode and kill people."

"Those are Canons. We are going to the canyon. It's like a small valley."

"Is a valley what's behind Alex's house?"

"No, that's an alley."
