When the weather's just right, amphibians in the Delaware Water Gap National Recreation Area are naturally looking for love. In order to help them in their love quest, a road is closed overnight . . . every mating season.
Since 2003, part of Pennsylvania's River Road is closed from 5 p.m. till 6:30 a.m. so drivers don't squash spotted salamanders, wood frogs, and spring peepers on their way to breed.
And the National Park Service invites people to come watch what they've dubbed the "lovers crossing" . . . and people show up! "I've wanted to do this for years, and I finally got here and we're going to wait and see what happens," Kate Andrew says. "I think it’s terrific. I think we need to do more of this kind of stuff."
