OK. I know most people don't want to talk about it for fear of a jinx. But city officials and� media organizations need to plan ahead. If the Patriots end up winning the Super Bowl, a victory parade will likely be scheduled for Tuesday, Feb. 5, the same day of the presidential primary.Some are concerned that this will be a nightmare. While others say Boston is a world-class city that can handle it.What do you think? Should officials try to pick another day?
