Our tower, though it's in a valley basin, is too close to the airport. Gotta call up the FAA now...

I guess we're small enough to not need to worry about Fort Harrison, but we exceed the FAA notification for HLN RGNL by 87mtr. What do we need to do in order to start(and possibly expedite) the "FAA notification" process? Here are our new determination results:

The region FAA was super-chill: "Yah wanna put up a tower? Where? Bah that should be fine! Just go through our online form and we'll let you know if you can do it in a couple months or so!" less than a month later: "Yeah. You can build. Thanks for letting us know there's a tiny tower there. You've got a year and a half to make it happen. kthanksbye."

I like working with these people.

Now that we know that the feds will let us build a tower on our roof, we just need to get permission from the land owner. Perhaps we can get the local upstart internet company to help us out. Treasure State Internet might be able to use some of our tower space! First let's talk to the land owner.
