Here is a Google map showing aerospace related entities - museums, government facilities, companies, spaceports, etc. This is via the Space Hipsters group on Facebook. I have added a few dozen locations myself and have snuck in three sport rocketry sites under the 'Space Novelties' category (in fact, at the time of writing all but one of those novelties are mine). I'm sure our hobby is a mere novelty to the general rank-and-file on that group but I thought we should be represented :).It's user editable so, if you want to add more, read the rules and go for it. I assume the owner will remove things if he doesn't like it. Like if we take over. LOL.
