Get drunk and party. Not that that I will do that. I'll be hitting up some back roads where no cops are around and having a little fun in my car. Last time I did this I ended up with a blown turbo....I boosted a little too high. But now that the upgraded turbos are in it will be fun.
Then later on in the day my friends will come over and we can sit back and relax. We will have crabs, either jumbo or #1's, and get plastered. Then it's off to play football (soccer for everyone else) which I completely stink at. I'll get tackled a hundred times and my baby will have to nurse me back to health. I love this day, I really do.
EDIT:
Oh and later on at night we will go watch the fireworks. It will be a lovely time.
