In Act 2, Scene 2. Is there a reasoning behind why Walter decided to go where he went after he quit his chaffeur job?

When he skips work for three days, Walter Lee explores the country and wastes his time. The first day, he drove Willy Harris's car past South Chicago and stared at steel mills all day long. The second day, he drove up to Wisconsin and looked at the farms. The third day, he walked around the Southside and watched all the colored people go by as he sat on the curb at 39th and South Parkway. After every adventure, he went to the Green Hat (a bar). He said the music at the Green Hat makes him feel like there is no other place that he should be. I think all the places he visited have to do with his identity or rather lack of identity. Walter is lopoking for a place to belong:to find himself.
