Alaska
Since 2006 I have been visiting a different place in Alaska each year, and hope to continue doing so.
2006: Wrangel/St Elias NP, Seward, and Valdez
2007: Homer and Kachemak Bay State Park
Great Falls is about 15 miles west of Washington, DC. There are parks on both the Maryland and Virginia sides. This visit took place when the river was extremely high. And that's a great blue heron in the last photo.
