I wish that I had taken pictures.
Here is one from virtualviz.com:
The funk on Lake Mendota today was horrendous--seriously.
They have posted the warning signs about blue-green algae along the shore outside the Memorial Union.
My favorite part in the warning is about the chance of seizures and convulsions in pets if they ingest the water. Nice.
And yet--this exists. It is a strange world we live in.
