You're right, that is a good idea that fills a niche.
I wonder if there's any demand for a "Barracks Rat" magazine. I spent nearly 15 years of my career in that category. It could be full of inspection hints, cleaning tricks for that latrine, how to roll the perfect sock, liquid or paste...the floor wax debate, it goes on and on.
For instance, the morning of an IG inspection, take a half cup of laundry bleach and throw it down the drain in the shower room...makes the place smell like a clean swimming pool. Worked every time...LOL
LOL! Who knows? Why don't you give it a try?
I have just found the right one for me. MORE Magazine. It is for Women over 40. Thank goodness! Shows we can be beautiful and attractive in our own right. We don't have to be 20 somethings to have value. :)
