There are a couple of approaches for the integration of Google Maps into Drupal sites - ranging from simple embedding, to a CCK Gmap field, to the dedicated and flexible Gmap & Location modules.
This talk will start with a stock install of Drupal 5 and step through the process of installing, configuring the Gmap and Location modules, collecting geocoded data and then displaying that data using Gmap's default pages and views queries returned by the Gmap Views module.
My Drupal/Google map implementation experience includes Happy Frog, DIYDharma, Car Free Vancouver Day, 30 Days of Sustainability, and Fearless City.
