We also heard from the presenters:

The presentation went great! They seemed really into the presentation.  Thanks for doing so much work on the AV and PowerPoint.  It was very age-appropriate (6th graders)  and interesting for them. Everybody wanted to build a skate park!  We did a few graphics building for the park features and included realism like constructing a shorter bridge is cheaper, special interest groups wanting hiking trails vs. motocross areas, etc. At the beginning and end I displayed MPEGs of terrain model fly-bys.  I didn’t expect a 10-minute conversation about 2D, 3D, and the 4th dimension, but got it anyway –sharp kids.

We survived! It was a lot of fun, actually. It was more fun and less scary than I thought it would be.

Many, many thanks for a truly great PowerPoint presentation and ArcView project. They worked wonderfully. I really appreciated the care and detail that you put into it all (down to the gender specific name tags!!!).  All of your hard work made what we did very easy and run very smoothly (esp. the second time through) and left plenty of room for ad libbing, adjustments and fine-tuning to the particular class!
