'Owl Prowl,' Hikes

An "owl prowl" has been scheduled by the Cornell Cooperative Extension for 5:30 p.m., Friday at the Suffolk County Farm and Educational Center in Yaphank. Spooky owl facts will be included in a lecture and slide show to be followed by a hayride to the edge of the farm field in hopes of "calling in" a great horned owl.

Refreshments will be served. The fee is $10 for adults and $6 for children 12 and under. Reservations should be made by calling the Extension Service's marine program in Southold.

Walking Dunes

The East Hampton Trails Preservation Society has scheduled a sunset/moonrise hike through Nap eague's walking dunes on Saturday beginning at 5:45 p.m.

Weather permitting, hikers will be able to watch the sun set over Goff Point from the toe of what may be the last walking dune, then stroll through the cranberry bog in the bowl of the dune as the full moon rises. Lee Dion, the leader, has asked hikers to bring a flashlight in case a cloud hides the moon, and to meet at the end of Napeague Harbor Road north of the intersection with Montauk Highway.
