I have a son who loves trains, and I have promised to build him a model railroad set. I am considering Scenic Ridge, but have two questions: 1. I need to store the set when not in use in a location w/ 12" clearance. Per Woodland Scenics, the set is ~16" high. Does anyone with experience with this set know whether modifying it to be 12" would be problematic? 2. Is this a set you would recommend to a neophyte? Many Thanks!
