Visiting a national park or state park or national monument or national seashore and going on the hiking trails there and/or fishing sounds like a great idea. It's just that I'm on the opposite side of the country so I'm not sure what is in that group is reasonable driving distance from you, plus is in a state that won't mind people from NJ at this moment. I recently went on vacation to a national park within my big state (California) and loved it. And I'm planning another trip to a mostly-natural area (though not specifically a national park) in another part of California around October (when some of the leaves turn there).
