Thousands of people last night jammed their way into Sunset Park, or their cars, that overlooked the roadway of the park, to witness the Fourth of July celebration there.

Traffic in the vicinity of the park became heavy soon after 7 o’clock and was seriously congested for the succeeding four hours.

During this period, it was next to impossible to move an automobile north of Newberry. Long lines of cars viewed from nearby hills, appeared to form a great, white wave as they seemed to crawl along the Lycoming Creek highway.

No estimate of the number of men, women and children viewing the fireworks could be made of those who saw the fireworks set off in the amusement park. Every vantage point within the park on the sides of the park was occupied with crows of people. West Wildwood and Mound cemeteries were crowded with automobiles. The roads and lanes about Grimesville and the hills to the northwest of Newberry had heavy traffic.

As the display ended and the crowds attempted to get away in their automobiles the main traffic arteries in the city were tied up. Police officers had to be dispatched to important intersections on the through streets to ensure a steady flow of traffic long enough to put through the north-south traffic.

The display at Sunset Park climaxed a Fourth of July in this vicinity that was unusually quiet. Unfavorable weather yesterday forenoon delayed early celebrations and forced either an abandonment or postponement of picnics and playground activities.

The baseball games attracted only small crowds because of threatening weather and portions of the municipal program scheduled for Memorial Field had to be abandoned for the same reasons.
