see the Denver Zoo. There are so many cute animals and it doesn't cost that much, but the food stands are costly, so I would pack a lunch.
Plus, there are so many shopping malls.
Fondest memory: all the parades. There is a parade for every holiday not to menchin parades for all the smaller cities. Like, Lakewood on parade, or the Arvada parade.
My favorite is the Christmas parade called, Parade of Lights. I was in it this year, and I had a blast.
