http://www.1800bepetty.com. I did the 3 lap ride along in Nov and it was a lot of fun. I think the cheapest driving package starts off somewhere around 300.00 and there are packages that are over 1000.00 and can be pretty time consuming.
From experience I can only tell you about the ride along - the entire experience took less than 30 minutes (it wasn't crowded that day). They did take one photo of me sitting in the car which I could purchase afterwards with a plaque for around 50.00. They also make a cd which you can purchase as well. There is an area for the family to sit and watch and take pictures. I paid around 100.00 for the ride along - and it was worth every penny. I wound up riding in the the car of my favorite driver by sheer luck. I was on cloud nine!!!
If your hubby is into racing at all, he'll really love this.
