I am not a vendor, so my view is somewhat different (selling trains is something I will leave to my heirs to take care of).
I had a great time at Cal Stewart. Ran the floor layout all day with my buddies, talked to old friends, met some new friends, picked up a new 400E, and had a great time. The meet was well run and organized.
There was a lot of postwar O-Gauge, original a repro standard gauge.
As far as the drive goes-I live in Alhambra about six miles from the Pasadena location. Even though I now have to drive a ways now, I don't mind a bit. Well worth it, IMHO!
