SQL Server 2005 Express Manager

Download details: SQL Server 2005 Express Manager December CTP

Many years ago, we were managing a $500MM project that had less than 1 Gig of raw data.

I used to teach SQL Server and Exchange, but its been a few years since I had a 'real' SQL project. Does anyone know where I can get a few Gig of raw data that I can use to test SQL 2005? I'm sure its out there. If I find a reasonable source (GIS data or some old test data that I can import), I will post a note with links or source information.
