ASTC: Science Centers' Best Kept Secret

I have been meaning to write about this amazing deal for a long time. There is an association of science and technology centers that allows reciprocal benefits for any museum on their list. Here's the way it works:
1. Go to the ASTC website. Read a little about this organization.

2. Scroll down and find where it says  Travel Passport Program page.
3. Click on that link and read all the rules for this program. (The gist is that they want you to visit science centers outside a 90 mile radius of your normal stomping grounds. *When I first used this program, I understood that I could go to any museums outside of a 90 mile radius around the museum I was a member of; now they also include the caveat that it needs to be 90 miles away from your home as well. I have never been asked to show my license, but that may have changed. To remedy this puzzle, CALL THE MUSEUM YOU WANT TO VISIT AND ASK!)
4. Check out the Participant list, May 1, 2017–October 31, 2017 and choose a museum to become a member of. Since I have a big family, I am always looking for a museum that says "parents and all children living in the household." Visit the website for that museum and order and pay for that membership. The last time I did it, our membership cost $70 for TWO YEARS. This time that museum was not available, so I bought a year membership for $60.
5. Visit any museum outside a 90 mile radius for free. With our $70 membership of two years, we visited Huntsville Space and Rocket and Tellus (twice) and got into the Planetarium at the Science Museum in St. Louis for a reduced rate. Just one visit to Tellus would have cost our family $78, and it has before too because we love it and have visited many times. One trip to Huntsville Space and Rocket Center would have cost us $124. So all in all, we saved $228 with the reciprocal deals!
