Several years ago I purchased black 3 inch corrugated perforated drainage
tube for fun tubes and for connections between cage levels.  The three inch
has become a snug fit for one of my boys and I wanted to upgrade to 4 inch,
but have had no luck at two Home Depots.  They had nothing of the kind (3
or 4 inch nor any of the connectors).  Surely this stuff is still being
used.  Can someone point me in the right direction before I start driving
all over the city?  I love this stuff - it's flexible yet stiff, lasts
forever, doesn't show dirt, easy to clean, makes noise when the boys run
thru, and I can spot them thru the perfs.
 
Thanks a bunch if you can help me!
