Some courses with slender maintenance budgets play "Winter Rules" (not always in winter), which means that if you find a bare spot or some other crappy lie in the fairway, you can lift/clean/replace.
My local 9-hole course doesn't even have a sprinkler system (!), so there are huge stretches of basically bare earth in the middle of some fairways. I found the owner once and asked him if he recommended Winter Rules, and he looked at me defiantly and said, "There are almost no spots on the course that have no grass at all." I suppose that was literally true, in the sense that almost every place would have at least a few pathetic trampled blades of brown that died months ago, but even so, I thought the claim was ridiculous.
But the conclusion is, I continue to play the ball as it lies, and I figure it's just one of the difficulties built into this particular course, even though it increases the frustration level quite a bit.
