As one who hasn't read all the beach regs, I can't honestly say whether the Council has ever addressed llamas on town beaches, or hippos for that matter. But even if it has come up, llamas on a beach, any beach, make for pretty nifty pics. Here is a blog entry I came across this evening about a family's visit to Pleasure Island. Check it out to view two full size llama beach pics.
PS. I wonder if there is a town policy on Grizzly Bears?
