• map location
  Yahoo maps at http://maps.yahoo.com/ is good for locating a place on a map.  You can enter a street address or an intersection.  For example, the Texarkana, AR city website gives an address of "E. 14th at Ash Street" for the Sandflat/Glendale Neighborhood Center.  Enter this for the address and enter Texarkana, AR for the city.  Yahoo will return a street map and the zip code.

• mapped census data
  FairData at http://www.fairdata2000.com/ automatically plots useful maps of census data.  You can go to http://www.fairdata2000.com/VoterRegistration/index.html for a list of states, but this won't get us to the useful stuff.  I can't figure out how their index gets us to the right place, but try going HERE.  This will get you to the address Sandflat center above, and from there, you can fiddle with zoom and pan and the dropdown menu for different maps.

• US Census maps and data to the tract and block level Go to the FactFinder homepage at US Census, located at http://factfinder.census.gov.  Near the bottom of the left column is a link to enter a street address; go there.  Using the Sandflat neighborhood center again, we'll guess the address to be 1400 Ash St. and enter that.  This returns a menu; click on "Block Group 3".  Next to the box are buttons for "Map It" and "Go". Click the "Map It" button and a window pops up showing us the boundaries of this area; it appears that we have guessed the correct street address.  Now click the "Go" button and scroll down to see links to data for this area below.  You can get to a smaller area by clicking on "Block 3007" on the menu list, and then clicking the buttons next to the list, or to a larger area by clicking on "Tract 202" on the menu list.
