We have the Slug
The House Rep. DeFazio who rolls the wheelbarrow behind the slug with a sign saying it is a slimy job, but someone has to clean it up (referring to Washington D.C./Congress)
And of course, a Slug Queen:
This year's Slug Queen went "green" & rode in a non motorized vehicle.
It was a beautiful sunny day & a nice break from all the serious stuff going on.
The only cutting edge parade entry was a statement against Corporate personhood
with a Corporate Pig!
