Amazing collection sir ,
I'm really glad to see another AFOL.
At first I also just collected em, once I got enough of them I planned to make a Lego city of my own collections, still there is a lot of work to do , plus u r right it's really hard to explain to family how does it feel being a Lego fan.
My city lacks some basic infrastructures like fire station, police station , hospital ..etc
Next time I'm gonna add these stations *.
Get a DIY table according to ur preferences for ur sets and put them altogether.good luck
