Short story entitled Guerilla Archaeology
‘I looked down from the police helicopter at the gridlocked streets. We landed near the cause of the chaos, and I walked to the hole in the road
I knew we were on the site of a first century Roman villa. The neatly excavated trench that spanned the full width of the main road confirmed my suspicions – this had been another ALA action.’
Hah, why not? That sort of (literal) guerilla archaeology’s been done in the real world. Have a look at pages 33-34 of this: http://www.ucpress.edu/content/pages/10636/10636.ch01.pdf
