At one point Facebook offered external profile tabs which could be modified and the implementation morphed slightly into a specialized Facebook version. That made it easier to share with friends.
Well, here it is 2016 and they've still not completely killed off the Travel Map yet. It doesn't work in mobile apps nor even in a browser on one's phone or tablet! Yet, if you happen to be on a regular laptop, then it can still be accessed from inside Facebook. Click the image to open yours in a new page.
This link loads for me on my laptop. In fact, I just added a few Scandinavian 'going to' places and made a few other changes. Exact mileage may vary. If you are unable to access the feature, I'd love to get a message from you.
Thanks.
