Looking for planters to expand container garden

Hi neighbors - we're planning on expanding our container garden and are looking for old pots that are still usable, old planters, or any object that could withstand being outside in the elements for a while (metal coffee cans, old roasting pans, galvanized buckets - use your imagination!). If you have anything hiding in corners of your basement or garages that I could repurpose, please let me know! I'm happy to pick up whenever is convenient. Thanks, Rebecca
