Similarities and Differences between McCandless and Thoreau

I think the similarities between McCandless and Thoreau is that they both go to the wild and take an adventure or travel to the American landscape. McCandless and Thoreau, they are looking of the beauty of the nature, and they both try the trip to the wild.
But the big difference between McCandless and Thoreau is that McCandless has a serious problem to the modern society, and he doesn't want to connect or communicate with other people. McCandless likes to get into the wild, and takes the only world with the lives which inhabit in the nature. Thoreau also intends to live in the attractive wild, but he has the connection with other human beings, not just wild animals or plants.
