There are lots of photographs uploaded to The Dumpster Truck page, under the Chapter Books tab.
These photographs were taken at the actual cafe that the Cockroach Caper series takes place at.
The truck in the photos is the actual truck the cockroaches went on. It is in the car park that they had to cross to get to the dumpster in Cockroach Capers Book 1: Kicked Out By Rats.
The driver of the dumpster truck very kindly allowed us to take photos of the process of emptying a dumpster.
