I've only been in the museum once or twice. You can see some pretty interesting artifacts that are relevant to the area and for the Michael Jordan fans, there's a little display of pictures of his early playing days (he graduated from Wilmington Laney High) and for some odd reason, one of his report cards.
This place will give you a good overview of the entire Cape Fear region. Pictured is the Michael Jordan Gallery. Widely considered the greatest basketball player in history, 'MJ' is from right here in Wilmington.
