It is a large, very well done convention. It is also exctremely costly to attend, not the tickets or door admission, the ancilarry costs like food, parking etc. Gaylord Opryland is one of the most costly sites in the country so if you plan to attend, take the credit card.
Weather in Nashville that time ofyear cna be anything from balmy to 10" of snow. I mention that because if you are from out of towna ndit snows, you may be there a while. Three inches snow shuts the town down and closes roads. I know that from experience. It is also quite wise to take ear protection. Turkey hunters simply cannot leave a call alone.
