what can you cover in a half hour?

[richsc]

I was asked to give a presentation to a middle school but in two separate, half hour segments. That's not much time to make any sort of point, but I worked in some concepts of the Roman army's professionalism, the Roman attitude towards empire, what the armor did (yes it's real sort of answers), the type of service soldiers did, but<br>
I"m not sure how that all went over. If you had a half hour only, what would you think are the top points to make that kids will remember? <p>Legio XX<br>
