Do you use database projects in Visual Studio? If not, then now is a good time to start. It is the best way I have found to source control my databases without actually sticking the database file itself in the repository. It is very simple to add to your solution and creates a default directory structure for your create scripts, change scripts and queries. Best of all the project will be recognized by source control and added to the source code repository. This means you can keep versioned scripts for maintainability. It also gives you the option to do the dreaded rollback!
