River

We took a small walk down by the river today.  We started off up on the higher banks.  They were throwing sticks and leaves.  Hard to get them into the river from up high when the wind is blowing. We watched a group of eight ducks diving.  They can stay under a long time.
Then we went down by the river and they threw in lots of driftwood that had washed up.  They had to "walk" the railing on the way back up.  Always expending energy.
