Parking the truck

The jeep stopped in front of a huge warehouse. Mark looked at the closed warehouse and sighed. It was locked from the outside. All of them got out of the car and looked at the huge shutter in front of them. 

"So, what should we do now? Should we search for another one?" asked Kevin, looking at David and Mark. 

David shook his head and said, "No, it would be a waste. This is the repair workshop for the trains. So there would be a place for us to park the truck. The other warehouses are for storing the trains themselves. So we won't have many places to keep the truck." pointing at the signboard to the side. 

"So, should we go and search inside the main block now?" asked Suzie. 

All of them went silent hearing her question, and they turned towards Mark for an answer. Mark looked at them and said pointing to the distance, "Why to go to the main block when we can easily find the keys there."
