We're at that desk. That same old desk. The questions come thick and fast. The audioconference fires up a raft of questions. The listserver shows other people in other schools have similar questions.

Virtual Field Trips can be an absorbing classroom exercise. The Real People in the remote location need to be well prepared for their role in the Field Trip. They need to be familiar with their audience and the time constraints of an audioconference. It's great too if they are expressive and passionate about their topic. They can assist in creating resources, stage manage audioconferences, upload digital imagery and web pages and contribute to the listserver.
