OFFICIAL CONCLUSION: RUMMAGE SALES REEK!
Special Note: If you are going to attempt to have a rummage sale and you live in the countryside, forget about it! You might as well donate all of your items to Goodwill or put them into a consignment shop. If the items are small and easily shipped, you might use Ebay.
For the amount of effort put forth into preparing, presenting, and cleaning up the rummage sale, the reward was quite limited.
