We continued our drive east and camped at a brilliant place - the Badlands in South Dakota, which we previously knew nothing about. Spectacular landscapes - vast grasslands, rocky undulating badlands. A copious cornucopia of interesting animal life - herds of bison, bighorn sheep, badgers, prairie dogs, birds of all kinds. North of the Badlands is a gaudy but entertaining tourist trap called Wall Drug... worth a visit, just don't stay too long! Starting the drive to Ottawa tomorrow.
