ran across a mother load of this stuff a guy wants moved...about 100 peices of differant legnths..thought i may pour it about 3in deep in the bottom and have it simulate a stump...may even drill 4-6in holes about 6in up from concrete and about half way up so small fish can get in it...what do you think..
