Walking Purchase Park Cleanup Event Planned for November 13, 2010 Download a Flyer (PDF) Walking Purchase Park Cleanup event will be held Saturday, November 13 from 9a.m.-12noon, rain or shine, and we will be focusing on the area along Riverside Drive. Here's how to get there: From West Third St., Bethlehem (near Perkins), follow the Detour Signs for Riverside Drive to West Second St. which will take you to Riverside Drive. You may park anywhere along the road's edge past the railroad tracks. We do hope that you can come out and lend a hand and ask that you kindly wear appropriate clothing and bring your own rakes and shovels.
