this is a neat little thing, shows the population of a zip
(just change the zip at the end of the URL)
the town I grew up in doesn't have a post office so its not on the map, next nearest town is the same thing, but the next town is where the mail gets routed to
Zip Code: 07830 PO Name: Califon (NJ)
Population (1990): 5526
check the tiger map and play with the census things below, its kinda cool!
