Here is a pic of our little honey booth. http://s203.beta.photobucket.com/use...G0221.jpg.html
We do a lot of the suggestions here. We have an observation hive, give samples, my wife made up little gift mugs with small honey bears honey candy and tea inside, she also had us shirts made up with our names, we ordered free pamphlets to hand out from the National honey board, and we are the beeks so I can answer most questions. The kids have really got into it and we enjoy it as a family and we are making some money.
The observation hive and the honey samples are big hooks! I have saw people go from not wanting any honey to buying a big bottle after they taste it.
