sorry for bumping an old thread, but for those in Ankeny, if you are planning on going to Cascade Falls this weekend, i'd get there early, otherwise, you'll be walking.
I took today off from work for a father/son day with my son and the 2 of us were there shortly after 12pm and it was all I can do to find a parking spot in the lot. After 2 hours, my son was asking to go to the pool at Prairie Ridge because it was soooooooo packed, he wasn't having fun....he spent more time standing in line for the boards, slides, and to get a tube for the lazy river.
