[nagdu] safari park question

[Martha Harris]

Hi Everyone,
Are safari parks and zoos exempt from the ADA? This weekend, I am going 
to one. It will be a wagon ride where people can reach out to pet and 
feed the animals. I have seen other safari websites that say dogs, 
including service dogs, are not allowed on the property. This park's 
site doesn't have any info about that. If I get there and they tell me 
my dog can't come in, do I have any legal standing to say they are wrong?

Thank you,
Martha
