Randy,
The buildings, fields, hills, etc are all components of my collection that I have either bought finished or bought unfinished and finished by yours truly. I've got loads of stuff and love coming up with an idea and putting it all out there on the table. The wheat field in this display was done by a scratchbuilder I do business with in the Uk, I'd say a good part of what I have finished in the way of figures, vehicles and terrain was purchased from Uk vendors, they do some terrific items in the Uk in 20mm
I plan on doing larger displays shortly, most of the ones I have done to this point are 4' by 4', I want to do several that are 10' by 4' as well....................
