Museums located within 90 miles of each other are excluded from the program unless that exclusion is lifted by mutual agreement. To receive Passport Program benefits at a participating museum, you must live more than 90 miles from the museum you wish to visit. Reciprocal admission is a benefit offered by your local museum and is intended for when you travel."
Are you saying that you've had no problem using it in your home state? Do they just look at the card & not check where you live when you go to the ticket counter? This would be a huge savings for us if it works.
Oh, it DOES absolutely work, but I don't want you to think that this something that I'm doing that is wrong or deceitful. The AMSE is a legitimate museum that participates in this particular reciprocal pass program. It is NOT required that you live in Tennessee in order to be an annual passholder to the AMSE. (I can't say for certain if absolutely none of the museums in the program have this requirement, but AMSE definitely does not.) With that said, as a legitimate AMSE annual passholder, you are allowed to in good faith use it to get free admission to any of the museums listed at the link I posted previously of the participating museums. The only checking of IDs at the gate are usually to match the name on the annual pass to the name on the ID to ensure that you don't have people "sharing" their family passes wrongly with other friends. As for Massachusetts specifically, they have honored it at the Quadrangle twice, the Children's Museum once, and the Ecotarium probably 7 or 8 times with absolutely no problems.
The "90 miles of each other" means that you can't use your pass to get free admission to another museum that is within 90 miles of your HOME museum. In other words, if I were to get a Boston Museum of Science membership, I would not be able to use it at the Boston Children's Museum. Since the AMSE is in Tennessee, it is definitely NOT within 90 miles of anywhere in Massachusetts obviously. IF the Tennessee museum is your HOME museum, you could go to any of the museums listed in Massachusetts (and just about everywhere else in the US that honors the reciprocal program) just as long as you are not 90 miles or less away from AMSE in Tennessee.
