STOCK Car Puzzle Mystery Cache

DO NOT look for the cache at the posted coordinates. Pauline Island is a big swamp and there's no geocache awaiting to be found there!

I'm a big fan of STOCK Car racing, you know, the kind that has cars going on in circles, mostly turning left (although there are two road courses on the schedule). I go so far back in the sport (and it is a sport), that I remember a time before The Intimidator became Saint Dale of South Carolina and he was downright HATED by fans. I have never been to a Super Bowl, but I've been to Daytona in February and that was my Super Bowl.

To find the cache, you will have to decode the following:

tkan fhsp kbos dpan woan vtsm xirm azyc pwkd urst ksyv wncu

Good luck solving this puzzle. An inactivated trackable awaits the FTF. I can't give a direct shout out to my favorite team, but you may recognize their name/numbers: 

Kyle Busch

Jeff Gordon

Jimmie Johnson

Dale Earnhardt Jr.
