around here sell base rock. It just looks like dead LR
. I got 3 pieces the other day to build a bridge(a small one). The cost was $1.69 /lb.
You can also get base rock from www.hirocks.com
. I have read people using this rock with good results. It is from Hawaii and the price is pretty good. I was going to order some but after getting my LR
in, I need to see how much rock I really need now.
