One thing too i like alot about this model is older pilots talking to younger guys, this is very common at smaller airports, folks hanging around on a nice day (before or after a flight) shooting the breeze. Other suggestions for additions to future lego fbo's are on out-house or restroom of some type, using the "can" before a flight is well....a no-brainer! Some type of outdoor game, basketball hoop, maybe a baseball or cricket bat lying around for something to do on those days were you have a low ceiling but no bad weather, possibly a radio for music for the same reasons. Also this maybe to modern for this type of era, but some type of UNICOM device, again common at small airports. I saw the mug in the crate so your good there, always stick with your first thought (like with the wind sock idea) and you'll make a good PIC.
