OBNWRQuarantine at the Occoquan Bay National Wildlife Refuge with Kelley Studholme
Green open space close to home has never been more important.

I love the Spring just before total leaf out, here in Prince William County. We are so fortunate to live in a place near the Occoquan River, Belmont Bay, Occoquan Bay and Potomac River; all of which are tidal, causing a constant ebb and flow of the water and wetland areas.
