Breastfeeding Question

I am due early July. We plan to take our daughter to the state fair at the end of August early September. my question is, if I am breastfeeding what the best method is so I do not have to breastfeed in public. I am a very modest person and just dont feel comfortable doing it at the fair. Any suggestions? I live about an hour and a half away from where the fair will be. I read milk is good for a few hours in the fridge but I won't have access. Maybe I could bring an ice chest? Just curious what your thoughts are, any tips help!!!!!
