We list 19 science centers in North Carolina that take a ASTC Passport Program membership, across 16 towns and cities. The largest clusters are Wilmington, Asheville and Raleigh.
ASTC Passport Program does not apply within 90 miles of the institution where you hold your membership, and in a state this shape that matters differently depending on where you joined.
Wilmington is the busiest single base: 2 of the 19 are within 25 miles of it, so one day out covers 11% of the state list. Another 16 sit more than 100 miles away, and the list spans about 284 miles end to end, so the rest is a second trip rather than a detour.
