On my old layout, which was fully "sceniked" (spelling?), I stopped the ballast right at the portal. You could see the foam, etc in there but I painted it a similar shade of gray as the ballast and left it. Doing it again, I'd have gone about a foot in the tunnel.
Again, don't waste time or money in a spot you won't see and that will be in total darkness.
I agree which is why I was wondering if there was a pretty cheap/free alternative. I will have viewing windows cut out in the plywood sides that support the mountain so I figured if I can glam it up on the cheap it would be nice.
I do have both play sand and cat litter but the cat litter is scented and the play sand is very light unlike the poster above with dark sand.
It turns dark when you wet it with the glue mixture. Just like it would if wet with water, only it stays that way.
