I'll make this quick, because there aren't many of them, and these tickets will go fast.
Click the link, use promo code: PTR, and buy them until they're all gone.
And if you buy one of these tickets, you won't just get to see the Spurs take on the Dallas Mavericks on opening night -- October 28th. There's the commemorative ring that everyone in attendance will be receiving, add in the experience of being there for the unveiling of the Spurs' fifth banner. Not to mention watching the Spurs receive their championship rings.
After the game, all who buy tickets through Pounding the Rock's link will be able to be in the first group of fans to stand on the brand new court themselves -- when they shoot a free throw after the game.
So what are you waiting for? There's a championship to celebrate. In person. With twenty thousand of your best friends.
