Melody Patterson, who played...

...Wrangler Jane in the 1960s sitcom F Troop, died at age 66. From her obit in the Times (my emphasis):

On “F Troop,” a comedy set in the Old West that ran on ABC from 1965 to 1967, Ms. Patterson played a feisty postmistress and storekeeper for a squadron of scheming incompetents at Fort Courage, a fictional Army outpost. Her character was also the love interest of the fort’s captain, Wilton Parmenter, played by Ken Berry.

In a 2001 interview with The Asbury Park Press, Ms. Patterson said she did not mind the innuendo between her character and Mr. Berry’s, even though she was a teenager at the time. “It wasn’t raunchy,” she said. “It was an innocent sexy.”

I did the math: Ms. Patterson was 16 years old when F Troop debuted in 1965. Are you telling me they couldn't find one actress in Hollywood over the age of 21?
