NFL Hall-of-Famer and legendary running back Earl Campbell with his custom Gossamer Gear Lightrek3 trekking poles. Living in Austin has its perks. Grant ran into Earl Campbell at a restaurant a few months back. Like some other folks that need an aid to get around town, Earl was using a cane. Grant offered to make a custom set of LT3's for him. Earl now prefers these to a cane and takes them everywhere he goes, including this year's Super Bowl.
