The major part of my experiment was going to be the integration with Google Maps. At first, I was a bit apprehensive about it, but Ruby on Rails being a community oriented language, I found a couple of quite useful plug-ins. With them, finding a location based on address or geocode or finding nearby places based on certain radius of a location were not too hard.
And I found that for things I wanted to do, I could do with YM4R/GM and Geokit. There are other excellent tutorials out there like the one by Jason Gilmore on Developer.com.
1. Sign-up for Google Maps API by going to here. For development environment, you can use either http://localhost:3000 or http://127.0.0.1:300 as the website URL. Copy the API key.
When you move to production environment, make sure you come back here to get another key for production URL.
