Provided the rain doesn't crimp things too much, there's something for everyone Saturday in northwestern Pennsylvania's state parks:
-- McConnells Mill State Park has guided tours of its namesake grist mill at 1 p.m. and 3 p.m. Go early or stay late for a hike along Slippery Rock Creek.
-- Help scour Cook Forest State Park for giant trees that might in fact break northeastern United States height records. If that doesn't cut it for you, try the Fire Tower/Seneca Point historical tour.
-- Check out the Wild Resource Festival at Presque Isle State Park.
-- Try geocaching at Moraine State Park.
-- Kids can learn about the Eriez and Seneca Indians at the Campfire Tales Native American Story Night at Presque Isle.
-- Farther afield, watch elk at Parker Dam State Park or Sinnemahoning State Park, or discover the moon at the dark skies haven of Cherry Springs State Park.
