Similar to deal last year, but at a different museum:
I can't get the groupon link - groupon seems slow right now, but it's easy to find. Just search for "Nuclear museum" near Albuquerque, NM.
If you buy today (3/29), there's an additional 20% off with code SALE3.
If you buy 3/30 - 3/31, there's an additional 20% off with code HAPPY20

From museum website [nuclearmuseum.org]
Your membership to the Museum means you have free admission to more than 300 science centers across the country. To learn which science centers allow you free admission, visit the Association of Science-Technology Centers.
You can call to activate the membership.
ASTC info [astc.org]
Per the rules, you cannot use ASTC member benefits with 90 miles of your address or the museum with which you have membership. We use the ASTC membership benefits while traveling.
At $36 for a family membership, the card pays for itself after one use at a lot of member museums.
