Longmire (2pm, A&E) - If you missed the great first season of "Longmire," here's a chance to catch up before Season 2 debuts Monday night at 10. "Longmire" is a slower-paced modern-day western (it's nothing like "Justified," but still pretty fantastic) based on a series of novels by Craig Johnson. Sheriff Walt Longmire is an old-fashioned Wyoming lawman who struggles to cope with his wife's death as he attempts to move on with his life and career. It stars Robert Taylor as Longmire as well as Lou Diamond Phillips and Katee Sackhoff. Do it.
Defiance (5pm, Syfy) - Another marathon. This one begins with the pilot episode of a new sci-fi drama set in the year 2046, more than 30 years following a war between humans and aliens that left Earth forever changed.
Ultimate BBQ Cookout Countdown (9pm, ABC) - A search for the top barbecue in the U.S. includes stops at the Talladega Superspeedway in Alabama; a clambake in Connecticut; a cowboy cook-off in Texas; a BBQ contest in Tennessee; and a Memorial Day cookout in California.
Crowd Rules (10pm, CNBC) - A repeat of Tuesday night's episode in which Mystery Brewing Company of Hillsborough competed against two other companies, including a fitness center in Myrtle Beach, for a $50,000 prize. Mystery Brewing's Erik Lars Myers (right) had to convince three judges and an audience that his business plan was the most deserving.
