Frank found a tourist pamphlet (seriously, that dude would read the ingredients on a soup can) and gave them a running commentary on what was what.

"This is the Propylon." He waved his hand toward a stone path with crumbling columns. "One of the main gates into the Olympic valley."

"Rubble!" Said Leo.

"And over there" - Frank pointed to a square foundation that looked like the patio for a Mexican restaurant - "is the temple of Hera, one of the oldest structures here."

"More rubble!" Leo said.

"And that round bandstand-looking thing - that's the Philipeon, dedicated to Philip of Macedonia."

"Even more rubble! First-rate rubble!"
