At 11 a.m. on Wednesday, police officers on bicycles from near and far made a pit stop at the Delaware County Law Enforcement Memorial at Rose Tree Park in Upper Providence for the 15th Annual Day of Remembrance in honor of fallen officers.

For Pennsylvania police cyclists, the 2012 Police Unity Tour kicked off at 9 a.m. Wednesday morning at Valley Forge National Park in King of Prussia.

The first leg of the four-day journey down to Washington, DC, begins each year at Florham Park, NJ, where the first tour was organized by Florham Park Police Chief Patrick P. Montuore in 1997. The tour makes stops at various locations and states down to Washington, DC.

By the time the tour made it to Rose Tree Park on Wednesday, the group grew to approximately 65 cyclists–including Delaware County officers as well as officers from Texas, Massachusetts and Georgia.

Four local police officers will represent the county in the 2012 Police Unity Tour. Those officers include Marple Township Police officers Jeff Haughey, Ed Hanna, Newtown Township Police officer Joe Vandegrift, and Springfield Township Police officer Daniel Boyd.

The tour ends with a ceremony at the National Law Enforcement Officer's Memorial and Museum in Washington, DC, and the money raised will go towards the memorial and museum.
