I was there yesterday (the show continues through today). Great show overall; better selection of all types of herps than in past years.
There was one dedicated cham breeder (Chameleon Addicts) who had a handful of younger Panthers for sale. His booth was not busy, which suggested to me more about the interests of the general herp buying public than about anything else.
There was one larger general herp vendor out of Fl (I don't recall the name, though if I looked through the vendor list I might recognize it) who had about a half dozen Meller's that were attracting a lot of attention.
LLL had a selection of about a half dozen species of smaller chams -- horned species and similar.
One or two vendors had young veileds.
I think I saw a display with a few pygmy chams of some sort.
That's it, I think, out of about 200 vendors. The herp hobby is currently infatuated with ball pythons and geckos of all sorts.
