Thousands of people streamed into J.F. Gregory Park Saturday evening for food, music and fireworks, but Luis Rodriguez Jr. only had one thing on his mind: the inflatable Mickey Mouse bounce area. “He’s already been in it three times, but I think he has more fun on the outside just looking at it,” said ‘LJ’s’ dad, Luis Rodriguez Sr. “He’s obsessed with Mickey Mouse.” LJ, almost 3, and his dad were paying their first visit to the city’s Independence Day celebration.
