The rivalry that exists is or should be good natured. The only bad thing I will ever say about Marines is that the food they used to serve to Marines was not palatable. In support of this contention I note I have never ever seen a Marine turn down an invitation to a Navy mess. I hope my comments on the food are outdated and they have the best now.

Palatable??
Heck, most of it was not edible unless you were starving, which we usually were.
If I had had a choice I'd have rather gone through the mess at the Salvation Army soup kitchen!
The main dish was usually SOS that could be thrown like a baseball and never drip a drop.
