Maybe a local caller wanting to know if you have clothes or gently used household items for the Vietnam Vets. It is a pickup service in Cincinnati, there are several around the country. Most times they call when there is another pickup scheduled close by to your address. I have used them before but I believe they have a "do not call" option so they will only call you to confirm a pickup that you request. http://www.pickupsforvets.org/schedulepickup.aspx Most of the volunteers work from home and use their personal numbers to reach out. BE WARNED! Some people will use this as a scam when they call so if unsure just call your local Vietnam Vets Pickup to find out.
