The link provided above states that the waiver didn't apply in the Texas case in question. It's like a lotta' other things, if you buy the right lawyer you can get around most anything you put your signature on and when someones kid is involved the parents usually buy the right lawyer, which is understandable but you still need to protect yourself as much as is possible. I say if these track owners and promoters want to expose themselves to the kind of liability that comes with having children in their pits then go right ahead. I surely wouldn't allow it and the parents could get as mad as they want to but that 15, 20 or 30 dollars you get for a child to come into a pit area may cost you your track, your house, your racecar or anything else they can put a lien on. It isn't worth it! It's hard enough to make a living owning and promoting racetracks and races without exposing yourself to unnecessary liability.
