Today we went to Mt. Vernon.
Three mysteries. One was this: If no food or gum-chewing is permitted on the property, why did the docent lady pop a stick in before she started her talk? The second is like it: If there are all these restrictions on food, why did they let dogs in (who might deposit something worse than gum on the ground)? The third is less interesting: Why was the green channel marker on the far side of the body of water we saw?
I thought it would be red: Red Right Returning (to port, upstream). So it should have been a red channel marker.
The only problem is that the channel is only 200 feet wide and we couldn't see any red ones from our vantage point. So the old adage holds true. Next time I bring my spy-glass.
