Seen this before at the post office and then somebody dropped it in my email...so I thought I'd pass it on!
"Flashing a driver's license when returning from a trip to Canada, Mexico, Bermuda, and most of the Caribbean isn't going to cut it in the near future. New homeland security laws proposed to take effect in the next 12-24 months mean anyone contemplating travel outside U.S. borders will need a passport or a similar document to re enter. Our advice: Download application info at http://travel.state.gov/passport , then hustle to one of more than 7,000 passport application acceptance sites. A new passport costs $97.00. Not cheap, but it beats a ruined vacation."
