WOOHOO! Good weather = time to build

I like the idea of using styrene (or I suppose you could use wood, but I'd use styrene) to form them out then pour in plaster. It'd be just like the real thing really. I don't know why, but I just prefer plaster for bridge abutments and piers. I don't see why you couldn't get a flat area using Doc's method, maybe use a palm sander to get it relatively flat and smooth? Doc?
