Big cactus

"Sixteen-year-old Benny Foushee, deemed by his father as going-nowhere-fast, embarks on a trip from North Carolina across the United States with his 84-year-old Aunt Lucy, his dog Polar, and his 1965 GMC pickup. Benny's quest, a challenge both overwhelming but irresistible, is to deliver Aunt Lucy to the big cactus, the giant saguaro in Arizona that she had dreamed of seeing since her own daddy put images of the American West into her teenage brain."--Dust jacket.
