thanks joe i'll remember that the next time i need tubing. i actually bought 24 ft at my local hardware store (for 20 cents/ft) and found a plastic connector at store where i work. we sell farm equipment and we had just the right size. go figure. just goes to show ya' that we can find stuff we need just about anywhere if we just start looking. and petsmart is 50 mi from me and walmart is 20 mi away so if i can make do here in town i do.
