This turned out to be an excellent re-introduction to web development, after I spent the last three years teaching 8th-grade science. My greatest challenges were:

• converting address files (in CSV format) to XML
• writing an XML_RPC client to access geocoder.us, which returns lat/long data
• fussing with XHTML and CSS so I could produdly put Valid stickers on my pages

The Google Mapping API itself is trivial.

Now I’m writing some filtering code to turn on/off map markers and show distances in miles from the school to various addresses. Yay!
