I think I got it.
I do have one question.
How would you do the following
I am building a directory
going to import 35,000 records
I want to list the following
1. just states using this url
domain.com/state/ list all 50 states, and then list cities with populations above 100k
then when someone clicks on cities, show census data for the cities
then when they click on the listing
show the listing
