I probably know less about how a computer works than anyone else on this forum, so I don't know if this information will be helpful or not ...
I've tried to access the page using the links provided in several places here, plus using my bookmark, plus using links available on other webpages, plus using links which appear when I use a Google Search. No matter which method I use, I get the same error message.
Adding to the fact that I am seriously techno-handicapped, now that I'm on a mac I have no idea how to refresh my page (if that's even possible on a mac), nor do I know how to clear cookies (if that's possible on a mac either).
So for now, I'm totally stumped. I have the day off, so perhaps I'll get in the car and go drive around the lake and check out the conditions in person!
If I decide to do that - I promise I'll bring my camera and post some photos from some locations that don't have webcams - so I can at least contribute to the cause.
