Be sure to take flyers to your local hotels and motels! Often visitors are looking for something interesting to do - one in every 14 households in the US has a quilter! So you might have a quilter visiting your town!
Include the hotels that specialize in business travelers - I used to look for quilt shops and shows when I was traveling as a consultant. And there are also "trailing spouses" (yes, that's what they're called) who are looking for a way to spend the day while their spouse is working.
Develop those relationships with the hospitality industry. There might be a great door prize in your future or you might benefit directly or indirectly from hotel/motel taxes collected in your town to encourage tourism!
