Parents and their young children can participate in the new Baby Steps Marathon! This weekly walking program takes place at 9:30 a.m. every Friday in selected Preservation Parks' preserves and other parks in Delaware County. Walks last about one hour; babies in strollers are welcome, but off-trail strollers are necessary since many of the trails are mulch or gravel.

The next Baby Steps walk will be June 24 at Gallant Woods Preserve, 2151 Buttermilk Hill Road. For a complete schedule, visit www.preservationparks.com and click on Programs, or call (740) 524-8600, extension 6.
