The cool weather better fit the Christmas season, but instead of red, green dominated downtown Lawrence on Friday as thousands thronged Massachusetts Street for the annual St. Patrick’s Day Parade.

This year’s 19th annual parade began at South Park, where about 100 entries gathered. They included floats, cars, Irish bagpipe players, motorcycles, bands and even green fire trucks, to mention a few. The parade ended in North Lawrence.

The parade entries weren’t the only attraction. People watching the parade donned various shapes of green hats, which sometimes covered green hair, shirts, and even green-painted faces. Dogs were dressed in green.
