Two months later:
Dingo's Calzones isn't dead, but it is definitely on hold. I couldn't find a location, and I was picky. Dingo's -- pizza pockets/calzones targeted at college students who want something different, particularly late at night -- came about because I found a product I loved. As cheap (some might say stingy) as I am, this is my favorite food, and a definite winner on a college campus. No doubts in my mind.
My first attempt at entrepreneurialism might have fallen short, but I'll be back -- maybe even with Dingo's. So in the meantime, I think I may catalog my thoughts as I go down this road, as well as comment on any business news.
Potentially, I have some ideas in the pipeline already, so my next venture might be close at hand.
