To dispose of unwanted items by leaving them by the curb for a few days ,Also beware of leaving stuff you want to keep by the curb as someone will think you are curbing it. Curbing rules 1. do not dump a box of curbed items out on the lawn to root through it. 2. If you want it take it , don't ask the homeowner to hold it for you. 3. Don't vandlize the stuff, someone will want to use it or recycle it.
Those old brake rotors I was curbing only lasted 15 min. before someone took them
