Your 8 year old will be hating life. You have to hang out till they re-open the road so you can come down, then you're in traffic forever. Even as an adult I dont like it. One good thing is you dont have to drink much to get drunk due to the altitude. Anyways......I would check out Fan Fest. It's free, Porsche will have some stuff set up, and it's pretty fun.
