Hi Guys,
Anyway, I notice in this thread a lot of discussion of "gluing" the ballast down and a number of pictures of rounded material similar to aquarium gravel, chicken grit, or miniature river rock. By its nature, smooth rounded material never really comes to grips with anything. It will fall into place and lie nicely next to itself, ties, and rails, but it will just as easily fall or wash out of place the next time it rains heavily or an animal strolls your tracks. Hence the need to constantly replace it and glue it down.
