Last year I made my own composter out of a plastic trash can, based on plans I got from a blog. The author said it worked great. For me, not so much.
I don’t know where that enterprising blogger lives, but it must be in a place where there are no squirrels. One of the determined little buggers, with the precision of a robotic plasma torch, chewed a perfectly circular hole about the size of a soup can in the side of my can. It then crawled inside to feast. On one particular day the trashcan was rocking like one of those wobbly tables down at the all-you-can-eat buffet joint.
Gotta buy a new trashcan and start over. This time it’ll be metal.
