Absolutely wonderful!
Crude question: does WS pay for these articles? I've used so much WS materials over the years, all with good effect, that I'd be happy to feature my layout--once I get it back up!
I don't have quite your magic, but I do some nice farmlands and meadows, and have used some of their materials in innovative ways with my photo backdrops.
Funny note: When I swept out the box truck after transporting the layout 1400 miles from Albuquerque to Ohio, I swept up a full shoebox of WS materials that had shaken loose on the scandalously rough Interstates in OK. Mostly ballast.
