Jason and Kristen Stravinsky navigate the shoreline below the dam at McConnells Mill State Park in Slippery Rock Township, Lawrence County, recently. Dustin Drew, park manager for Moraine and McConnells Mill state parks, said that while a shallower Slippery Rock Creek may hinder white water rafting, the key concern for park rangers at both parks is the dryness of the vegetation. He said dry grass and vegetation could catch a spark easily and cause a wildfire to spread quickly. “I think we’re a little more observant of the grilling and charcoal fires,” Drew said.
