I posted some scenery oriented photos in the Gallery under Pond Junction & Stony Creek RR. "Rain" is actual water sprayed from above as picture was taken. Shiny "ice" is freshly wetted plaster. "Concrete" bridges are painted hardboard. "Stone" bridges are hardboard with a thin layer of plaster, carved and painted to look like stone blocks. "Snow" is plaster of Paris sprinkled from a sieve. Enjoy!
