It looks like Highland Park has finally had it with all of the porta pottys cluttering up their hood. They're now going to require all porta pottys to be screen from public view. Unfortunately their idea of a screen is far from a significant architectural statement.
Fortunately the good people at HPD Architecture have decided to get involved. They're hosting a contest to see who can design the best porta potty screening wall. They're even planning to give out prizes and build the winning entry! You can read about it here - screen my potty.
