Wonder how long hard-boiled eggs would last on a driving vacation, without refrigeration? We like them for snacks, and I guess I can take an ice chest if necessary, but just wondered if anyone had any idea. Seems to me I remember when I was a child, having dyed easter eggs laying around quite a while, unrefrigerated. We actually didn't even have a refrig. "way back then." They kept fine, but I don't remember how long.
