When ballasting time came, I had trouble getting "real" model ballast and began using kitty litter. I found the litter pretty satisfactory in every respect but one. It cracked a lot when put down in larger areas, like a yard. No big deal really.
After I was into it, I was able to procure Brennan's product. yes, much better although I am, in no way, unhappy with the "Kitty Litter Division" of my layout.
Glued down was my preference. No opinion on leaving it loose although definitely inappropriate for my hinged entry way gate! In fact I keep losing ballast there even though I glued it down.
