Some years ago I fell asleep on a sandbar.
When we arrived, we dropped anchor. There were some hundreds on the sandbar- then very large. The hundreds were happy. They were not wearing very much clothing and they were laughing.
When I woke up, there were less than thirty of us and the sandbar was a great deal smaller than it was.
It was all very silent.
I could see our brigantine anchored in the middle of the river.
I could see our barque-rigged whalers sitting swept-cross beached near to me.
My sleeping bag was very damp. The water was lapping at it.
My feet were sore and stiff.
I suffered from immersion foot for the next three days.
