That's good, Paul. I realize that of course some people - too many people - do not act responsibly. I guess that's why we have so many laws. (Although I note that in Central America they have less laws and it doesn't seem to be that much worse... in fact in many ways it's better, but that's another thread for another board...)

As to Rick's question as to how a "no dog" rule or law would be enforced, I say that if it were a law, it would be the same as the No Camping law up there, it could only be enforced when the rangers came through. But if a few people started getting tickets, wouldn't it curb the practice? And if people began to say, "Hey, did you know dogs aren't allowed up here?" that might help as well...

But, hey, I have no problem at all with dogs being up there until or unless it is proven that they are causing a problem. And so far that has not been proven.

That is why my thread was stated as a question, not a statement, and why I suggested that a test be done to find out.

Meanwhile, what else could be done to minimize the problem or potential problem of the protozoa?
