My first visit to the Great Wall was when I was a wee little five year old lass.  My mom, grandma, and I were in Beijing to get our visas/passports to move to Canada.  Evidently, you had to personally go to Beijing to get these things, back then.  My memories of that trip are extremely fuzzy, but I do remember desperately wanting to climb “to the top” of the Great Wall.  Whatever that meant.  And I remember being disappointed, when my mom, wearing incredibly impractical shoes, refused to go with me. Fast forward to 2015 and I was in Beijing again, with my Dad and Mom, for medical reasons…
