title: Integrating a google map into rails
body: <p>Has anyone got any suggestions on where to start with building a google map into a rails app? I would like users to be able to add a marker by clicking the map, and have spent a few days looking for a suitable tutorial or plugin (beyond ym4r), to little avail...any help would be much appreciated as I am finding the Google Maps API rather difficult to get into! I've also come across the railskit for google maps - does anyone have any experience in using it?</p>
