‘Parks and Recreation’

This sweet and funny comedy about various government employees in small-town Pawnee, Ind., closes out its sixth season by sending Ben and Leslie (Adam Scott and Amy Poehler) to a national parks conference in San Francisco. And even more exciting, Ron (Nick Offerman) has an encounter with his ex-wife, Tammy 2 (Offerman’s real-life spouse Megan Mullally). Season finale, 8 p.m. Thursday, April 24, on NBC (seattletimes.com/tvlistings).
