I do the same thing all the time!

I am always looking up--Planes and helicopters overhead? Pull out planefinder.net on my phone to see what that one is. Hell, even birds :) Catching an eagle or hawk doing their thing up there, just awesome.

Not sure if this is your thing, but I subscribe to NASA's Spot The Station which gives you a heads-up when the ISS will be passing over your location. Includes the direction in the sky it appears, the angle above horizon, duration of visibility, and where it will leave your visibility.

After several years of subscribing, I still go out to watch it 90% of the time it will be overhead--about 2-3 times a month or so. (Unless you're a sick-in-the-head morning person who is up at 4 or 5AM in which case you can see it a couple additional times monthly).
