We list 41 museums in Texas that take a NARM membership, across 22 towns and cities. The largest clusters are Houston, Austin and Fort Worth.
NARM does not apply within 15 miles of the institution where you hold your membership, and in a state this shape that matters differently depending on where you joined.
Houston is the busiest single base: 10 of the 41 are within 25 miles of it, so one day out covers 24% of the state list. Another 29 sit more than 100 miles away, and the list spans about 674 miles end to end, so the rest is a second trip rather than a detour.
Because the benefit is built for travel, the states next door are usually where the card earns its keep.
