Memories from our childhood can often get mixed-up or muddled, as nostalgia wins out over everything else.

The Tempe History Museum might help you clear that up on Thursday — or you could just feel sentimental — as a panel talks about the Legend City amusement park, which closed more than 30 years ago, and Big Surf.
