There's a flurry of things still to be done.  "My head swims with how busy we're going to be," Stan Meadows, Grizzlies senior corporate counsel, said Tuesday.  A choice between two locations for the new arena is needed.  Final arrangements must be paid for upgrading the Pyramid.  At the same time, a judge refused to dismiss a suit to block using public funds for the new arena.  The case will go to court July 9, although most people are downplaying its significance.  Perhaps more of an issue is a petition for a referendum on public spending for the arena, but that's unlikely to have enough signatures before the NBA decides on the move.
