Rockies 一共去了6次。

如果加上Denver/Estee Park Nal' PK, Yellow Stone, Grand Teton, and Glacier National Park, Grand Canyon shouldn't count.

Among all from South to North, Canadian Rockies in Banff National Park is the best. It has the best snow peaks, prettiest lakes, Glaciers, countless waterfalls, hot springs, wild animals, etc ... Yellow Stone is the worst.
