When I started working with rails at UW-Eau Claire I began my journey by reading Agile Web Development with Rails so I figured the best way to grasp all the changes with Rails 3 would be to purchase the updated version from Pragmatic Programers and walk through the famous "Depot" example.
Since for the last year I have been primarily fixing both rails and .net websites and have only done a few new projects I really wanted to dive head first into Rails 3. I found the Agile Web Development book to be a great way to do that.
So if your looking for a way to ramp up on Rails 3 or just to learn Rails in general stop by http://pragprog.com/ and pick up a copy of the book.
