Here are my suggestions, take them for what it's worth:
Publish a Blackpowder Mortar and Cannon CALENDAR!
We have plenty of material - who wouldn't want their mortar or cannon to be "Miss September"?
Do a different one each year.
Action pictures.
Details of some of the fine work done by our sponsors!
Historical pictures. How about a pix of the DICTATOR in front of the Iowa captial building!
(Might even get Goex to chip in a nickle or two.)
Next suggestion - T-shirts: White? How about ARTILLARY RED?
Matt - get ready for folks sending their BEST pictures in, they know how to send them to you!
