Remind me to acclimate if I ever even think about the Rockies!

I haven't been to Denver in ages. I was younger then but not only did I get dizzy skiing but my Dad got altitude sickness bad enough that he would up in the ER.

I am convinced that non-acclimated tourists having their hearts beating a bit faster is why people always seem so unhinged at places like the Grand Canyon. Like they feel a bit worked up to start with and spiral easily.
