Rich Dad, Poor Dad....

Have any of you read this book by Robert Kiyosaki or attended any of the seminars hosted by his organization? There are some free seminars coming up in the Cleveland/Akron area at the end of the month and am wondering if it's worth my time to attend. From the surface, it looks like yet another way to get wealthy through real estate. But if I don't have the starting capital to begin with, how do I invest?
