Hey I had airports I played with when I was a kid. I had them in my basement. Looked nowhere near what you have. Very primitive looking with all different scale models and cardboard boxes for terminals! I had orange race tracks for the edges of my runways with pistachio nut shells for runway lights!!! But I spent hours playing in the basement and my mom would have to come downstairs to remind me I had homework to do.
As you progress in your skills as a model airport builder, it'll look better. I bet your friends don't have anything like you have and probably wish they did! Keep it up and most importantly. Have fun!
If you love something let it go, if it doesn't come back, track it down and kill it.
