Not a lot of bears to worry about on my side of the Cascades. Just a few hungry racoons with a bad temper! I built my compost bin out of pressure-treated 2x4s & hardware cloth. I built a lid & a door with hinges so I could move the bin easily & turn the compost. I think I only spent about $50. I used a nail gun & gorilla glue to build the frame & hardware staples to attach the cloth. It was an easy Saturday morning project. Are you planning on hot or cold composting? That will make a difference in the bin you use/buy/make.

Warm regards,

Larry
