This fellow is either headed to his left to Union Station to take a trip on Amtrak. Or he's headed to his right towards the bus station to take a trip on Greyhound. Could be he's just arrived on the bus and is walking around until he comes to a bus stop or a MAX stop or a cab stand. Oh, I just realized that maybe he road on the Greyhound from somewhere east of Portland and is now walking to Union Station to continue on his way to somewhere that he can reach by train.
My best guess, he's going to his left to catch a train, all clean and shiny, unwrinkled, walking with a spring in his step. Take a good look at that rolling apparatus, loaded carefully. And his backpack appears to be packed, too. Plus, I've never seen jeans with pockets made of a different fabric--the one that we can see on his right leg looks stuffed to me. I think he's on his way to somewhere that he's prepared to visit for a while and where he plans to have a good time. I hope he enjoyed himself as much as enjoy seeing this sunny sight. I took this photo across the street from Union Station on July 24, 2010.
