Took a look at the posters already.
Bill had a poster about his Digital River Project. The associated website is pretty awesome and sounds like an amazing way to get the public involved.
There was also a poster about digital field recording. I was not really the target audience, but it was very well put together and their GIS seems well formed. I am glad that I am seeing more and more of these. After years of being told that it was not a good idea or that it would not work, I am happy to see more and more people so succe and in their attempts that they can bring it in this forum.
