We are leaving on April 9, 2017. My dad and I are sharing a channel on YouTube. Anyway, history time: Hadrian's Wall was built to keep the barbarians up in Scotland from getting into England, it was built in the year 122AD (go to DK find out to find out more about it!). Hadrian's Wall runs from the East Coast to the West Coast of England. I'm going to hike across a whole country!! Here is the link to DK where you can find out more:
