I LOVE THE TUNA GUYS!!!!!!
I was only on the playa for 2 days this year
::better than not at all though::
and I couldn't find the tuna guys,
they have been one of my favorite camps for the past 5 years.

VIVA LA TUNA GUYS

Correct me if I'm wrong,
but didn't Duchamp's "Fountain" have graffiti on it.
something like R.Mutt 1917

The original piece itself was not pristine
so maybe some clever burner was commenting on your oversight
