Try not to stand underneath the uhhhhh leakproof covering because you will be drenched if its pouring like it did last night. After Calvin Murphys Tv plug for his bobblehead doll the other night against the Lakers, when he presented a signed one to Jack N I would say show up 40 minutes early.
I would suggest going at least a hour early before the game. Meaning be at the stadium doors at 6pm. They usually open the doors at 6pm for a 730 game so i assume it will open at 530pm instead. Before I would get there before the doors open but I have gotten there anywhere from a hour to 45 mins before tipoff and still manage to get a giveaway.
