Your not going to have any success spotting inside the terminal, unless you have a borading pass. They don't let you go into the gates area unless you have a boarding pass. I'm guessing if you do have a pass there should be some pretty decent views from the gates area. About your other question, if you go from one terminal to the other your going to have to go through security again. Hope this helps.
Will you watch the Cleveland Browns and the Detroit Lions on Sunday? Only if coach Eric Mangini resigned after a loss.
