Michael makes a good point about the predicted wind conditions. While I think we can all tolerate a gentle-to-moderate breeze, winds in the 10-plus mph range start to become a real issue for equipment and quality of views, not to mention interfering with just general enjoyment level for visitors and presenters.
I remember an observing session out at the Ebenezer site a number of years ago that was windy. There was a real problem with fine sand particles from the beach being kicked up and sent aloft to saturate the air in the area. It basically served to create a sandstorm in the midst of the session. Needless to say, these were not good conditions for delicate optical surfaces and mechanical systems in telescopes.
Although we have had a lot of rain over the past couple of days that could ordinarily help dampen the beach sand and make it less likely to become airborne is windy conditions, my fear is that the winds we've been experiencing throughout the day may have served to dry out the top layers of sand again this evening.
What to do?...
