Howdy, Tin. Yep, OPSEC is important. There's already been some great suggestions for disposing the cans in this thread without drawing attention. Maybe somewhat risky...cut them into "hobo stoves" and leave them around for people to find for use as an emergency cookstove?

There are a lot of ways to repurpose the cans for survival but with your storage space they may still be problematic. https://www.survivopedia.com/10-tin-can-projects-that-can-save-your-life-one-day/
