This is Nanna. She's a blind and deaf senior on a mission to visit every bridge in the Twin Cities. Three years ago she was given only a few months to live, but today she runs 10Ks with her dad. So far, they've made it to 9 bridges and have 18 more to go. 14/10 #SeniorPupSaturday https://t.co/zMIjpmofgJ
