I have been to all of the gatherings (as has KCDano, Coley, Charlie Mitchell, & DLAery) since the first one. It is not a formal affair just a bunch of guys getting together to build, show, talk, and trade lures for a few days. We meet at Nathan's house and gather in his shop.
As far as food goes, we have, in the past, grilled burgers, had a fish fry, and Coley put together one of his "Hobo's".
You might also consider bringing anything that you don't use any more or that you would like to share or trade. Things such as, lure blanks, lips or bibs, paints, wood or other lure materials. After all, we are a bunch of pack rats.
Understand that Clinton is not a big town but it has just about anything that you would need. There are several restaurants and a few other hotels besides the ones that have been mentioned. Nathan's house is about 8 miles outside of town. It's not hard to find.
If you have any questions or need any help, let us know. We'll do what we can.
