In the 80s, Ron and Ann Newark bred Miss Reed Chex to Smart Little Lena, and the resulting foal was a filly they named Lil Miss Smarty Chex. She was shown at the Snaffle Bit Futurity in 1990 and ended up tenth overall. The mare won the Open Hackamore class the following year at the Futurity, Ventura, Salinas. She was Open Reserve Champion at the Stakes and at the Cow Palace Grand National Snaffle Bit Futurity.

The Newarks decided it was best to end the mares show career early and breed her to Nu Cash. With Nu Cash, she produced Smart Little Cash, NRCHA Snaffle Bit Futurity Open Champion, Annies Nu Lena, SmartCashInvestment and Annies Little Cash.

Lil Miss Smarty Chex caught the eye of Carol Rose, and she leased the mare. She has several very successful foals out of Shining Spark including Smart N Shine, Shiners Smart Chex, Lil Miss Shiney Chex, and Shiney Lil Miss.

Lil Miss Smarty Chex was humanely put down after problems with her stifles. She was the number one producing mare in the NRCHA for many years, and will always be remembered.
