I too agree shelving the event shirt for one that is Stovebolt.com in nature for a few reasons:
1. Customability - If the same shirt company is used as before, the purchaser has the ability to take the given design and place it on the color of shirt they choose.
2. John spends a TON of time making these items for sale for the site.
3. Most importantly, the proceeds for the shirt go to Stovebolt.com to help fund the sight.
