Good luck DK. If just one person shows up it is a start. It takes time to get the word out.
Maybe you should try to think of how you can spread the word. I don't know maybe make a flier and see if you can post it in the hospital and doctors offices or see if some of the alcohol counselors will let you leave it in their offices.
Anyways just some ideas. Hope it all goes well. I am looking forward to your report when you get back.
