Some sites for my mom:

1. Regulations.gov
— Agencies post pending regulations for notice and opportunity to comment.

2. GPO Access Home Page — primary law sources for all three branches of government. US Code isn’t up to date (of course) but the CFR and Federal Register are. Includes a List of Sections Affected current as of today. Navigation’s a little tricky though.

For the rest of you: Spirograph!
