I forgot about this project i did a few years back.
Under all the rocks & stuff are a piece of 3" pvc,with a 3" 90* on one end & a 3" 45* on the other,thats in the back.
It also contains 2 pieces of 2" pvc,both w/ a 45* on one end & a 90* on the other.
So there are 3 different tunnels,with 6 openings,plus the small cave in the front.
On top are the rocks,wet plug cement,egg crate,& nylon screening.
Wish I had better pics.
