Creating a time line of the events (Assisgnment 2)

While I was reading this book I had a really hard time understanding what was going on. Usually in other books the author introduces the characters, settings and situations at the very first chapter. But in 'the road' no details where shown. Another weird thing was the protagonists do not have names. Just 'the man' and 'the boy'.
Anyway page from 3 to 50 doesn't really have noticeable events. At the beginning, from page 3 to page 11, the man wakes up in the forest and checks out if the boy is okay. Before he woke up he dreamt a dream. The man had wandered in a cave where the child led him in his dream. In the dream he encounters a beast, dripping its mouth and staring with eyes white and sightless which was eerie. The man starts to walk out to the road and checks out if everything is okay. He then goes back to the boy and plans to move on. An hour later the man and the boy were on the road carrying their knapsacks. They cross the river and reach a gas station. While the man travels to south he picks up things they need for survival. While they pass through the road they see a city. Burned houses, fallen trees and abandoned stuff was the things he could see through his binoculars. After that it starts to rain and they wait until it stops. They prepare for the night packing things they need. In the morning the man and the boy starts the day as they did yesterday. They pass through the city with caution and finds no sign of life. Just dark, grey ashes. In page 18 the man dreams about his wife. Pale, wearing a dress of gauze. He woke up in the morning, watching the snow. Till page 20, nothing occurs and they go south then arrives at a dam. They meet another abandoned city called See Rock city in page 21. At the city, in a supermarket the boy has a chance to drink Coca Cola. Then they go on. After a while they came upon an old frame house with chimneys and gables and stone wall. It was the house where the man grew up. They go in and the man thinks about the time when he stayed and reminds of his childhood. However the boy urges the man to leave the house because he was scared. Three nights later in the foothills of the eastern mountain an earthquake happens. The man dreams of his wife once more but it was a dream about his wife's death. In page 39, they stay in another forest with nothing alive in it and swims in the river. The boy feels comfort here, having morals for meal, watching the wide river. But later the man in page 41, convinces the boy to leave because it is not safe. While they cross the river it rains and they stay a night in a truck. In the morning they pack their things again and go under the truck to pass the bridge. This happens from page 44 to page 47. From page 48 to 49 they figure out that somebody had come out of the wood in the night and walked down the roadway. In page 50 While they stroll down the road they see a man shuffling along the road before them , dragging one leg and stopping from time to time. They observe the man as they follow him. Later he drops to the ground and does not stand up. The man was covered with dark ash and his eyes were burnt shout. The man guesses that he was probably struck by lightening. The boy wants to help the collapsed man. But there were nothing they could do for him so they leave and the boy cries.

As I said at the beginning there was no specific events through page 3 to 50. So that made it more tricky for me to line up the events that happened.
