My suggestion for next year: if you want to see Augusta National, show up on Tuesday of Masters Week for a Practice day.
When you exit I-20 and drive down Washington Avenue, there are loads of scalpers selling Practice Passes for under $50. Don't doubt this, because I've done it a number of times. Food on the grounds is stupid cheap ($6 will buy you a sandwich, chips, drink).
When you arrive, check the board near 9th green to see the tee sheet for the day. It changes constantly because the players sign up randomly on Tuesday. In the morning, walk all 18 with one group so you can see the place. (Warning: they may play only 9 and then take a break).
Then in the afternoon park yourself for an hour at a few of your favorite spots.
Bring a chair and an umbrella. You can leave your stuff sitting near a green without fear of being stolen. That way you don't have to carry it with you as you walk.
NOTE: you can also scalp for Tournament Tickets, but you should be prepared to pay a hefty price.
