You'll have a blast.
As you drive through the small towns, the residents will fill the streets and treat it like a parade.
Last year was a blast! We had nearly 4000 cars haul from Arlington, TX to Green Bay.
Be prepared for long traffic delays. When you hit the small towns, many of 'em will direct traffic through the towns quickly. Mid size towns will experience heavy delays and 2 or 3 mile backups at traffic lights. Larger cities will be able to handle the traffic.
Remember that it's not about the destination. It's about the drive. Don't take short cuts. Don't try to beat everybody to the destination. Just sit back and cruise with a few thousand of your hot rodding bretheren.

Helluva deal.
