Rick,
Evan Stahl (I believe that's how his name is spelled?!?!) was actually there at the show as a vendor. The "authorities" after having found nothing criminal at his table, asked him several times to help identify what was at other tables. I believe he said that he agreed to do this so that no animals would be seized incorrectly.
However, outside of the building (where no one was helping in this way) people were having their bearded dragons confiscated for lack of an aquaculture license. However, as I noted before, bearded dragons are desert lizards! Another point of interest though, is the requirement of people to have an aquaculture license in IL applies only to native IL species! Again, beardies come from Australia, not Chicago.
Evan was there, and he reported this all on the BOI (another website run and owned by Rich Z.). So far, no one has disputed any of it.
Hope this helps --
