Lewiston's Hot August Nights kicked off in August of 1987, and began as a way to bring the Lewis Clark Valley a taste of great music and artists they never had a change to experience before. After the initial success of the first few years, a classic car show was added to the mix. It has quickly turned into one of the Valley's favorite summer events.

As time has gone on Cat-FM has grown, acquiring three additional stations and an online news site Dailyfly, now collectively known as Pacific Empire Radio. As the company has grown, so has Lewiston's Hot August Nights and the non-profits they have partnered with. The classic car show has turned into a fruitful fundraiser for the non-profits, with over three hundred cars from all over the US participating.

Lewiston's Hot August Nights is truly a community event! Downtown Lewiston's streets are closed down so all the classic cars can be displayed. The event kicks off on Thursday at the local Toyota dealership (Rogers Toyota) with a preview of classic cars on their lot. Friday night is a valley favorite with the classic car cruise. All these events lead up to Saturday's car show and award ceremony, where old friends meet up and take in the sight of cars brought in from all over.
