Living up in the mountains, we are a few hours drive from the ocean. We have a stream next to the bush track near where we live to wallow our feet in instead. It has little fish and yabbies, and it can have a strong current just like the ocean if there has been a lot of rain.
The environment is constantly changing at this spot. Some days there is more sand than others. The yabbies often come out to play, but this day it was a bit cold for them.
