Take a tiny stroll away from the car after a thorough washing to admire your efforts, and pick up a cache as your bonus for a job well done. No bushwhacking required - look around a bit and be on your way. Cache is located relatatively close to I-20, so take a break and get your smiley.
Small cache with quite a bit of kid swag, but feel free to bring some more. Adequate space for trackables. Small compass for the FTF.
