Hi David: Networking can happen with field trips. I think the cool thing about field trips is they can really inspire students to try harder in class based on the experience. Sometimes, some students get a vision of a really awesome possible future, and that vision can be strong enough to change how a student studies, or how hard they work. They want to be successful, and maybe they perspective about the profession was only a vague idea. Now they have something solid to shoot for! Regards, Barry
