Be really careful on your dates, or you will conflict and possibly limit your potential growth. You mentioned tax return time. February 18th is the St Louis show. New York is March 11th. Raleigh-TAPS is April 8. Next biggie is Chicago and people will be saving their pennies for that one. It will tie up May 3-8 this year. Do not be surprised if it is difficult to get a show in between.
