The silo would be a nice addition to your "mini diorama". I noticed on one of the loading videos that you were having a hard time with the dragline keeping up with the conveyor. Just need more practice
. Or perhaps a larger collector on the conveyor that you could fill before starting it and maybe then the dragline could keep up. Just a suggestion, you are doing a great job. I am a "water nut" and if I had this set-up 20yrs. ago you would have never got me away from the site.
