More of the the glacier here.
OK, when the fam went to the Grand Canyon in sixth grade my father was worried that me (and my mom) got too close to the guard rail-less edge. It's become a running joke in the family for my dad to say "don't get too close." He of course reminded me before this trip. Hell, when I went to AZ with my friend Jon, even he got in on it (but seriously, because as usual I like getting close enough to see over edges).
