I have completed the CafePress Boomershoot 2017 section. The image used was the beginning of the fireball from Boomershoot 2015. The slogan is from a comment by JFT on one of my Boomershoot postings.
In addition to the usual t-shirts, cups, and thongs (yes, there has been more than one sale of a Boomershoot thong) there are now king-size blankets, coffee trays, cutting boards, pillows, and potholders. For some reason a potholder with an image of a fireball on it makes me laugh even more than the Boomershoot thong.
Take a look and see what you think.
