Hey, i am big fan of do-it-yourself. I have been diy'ing stuff together for fish tanks for years. Like you said, why buy if you can diy?
As far as deranged chipmunks, only when we are cornered do we try to eat faces. It's those darned propogandist squirrels trying to ruin our good name! Personally i think they are still ticked that disney chose chimpmunks over squirrels for the chip and dale roles!!
