Greenberg shows in various parts of the country. Various regional TCA, like METCA here in the NYC area, have shows in the fall. First Frost in Allentown to me is a good one (in November). Where do you live,? Are you willing to travel? Big country, lot of shows
*added note: Your profile shows CA, I don't know if that is current, but I did a google search on "California Train Shows" and it looks like there are events in the fall and esp around the holiday season....
