Snakes are important

Brendan (and Kieran) loves to watch the planes as we drive by the flightline every morning-it generates great excitement and sometimes, interesting conversation.

From Tuesday:

Brendan: I hate the trees.  They should cut them down.  I can't see the plane.

Mommy: Sure, snakes too.
Brendan: Are snakes important?
