If you have the 64x64 plot in the Get Together expansion... the plot of land I have, there is a creek behind the property with a fishing sign. I thought they needed a parent with them, but they can go by themselves without traveling. You can go from the house, to the creek, click on the fishing sign, and they will walk to the creek. When their moods get low, you can click go home, and they will walk back home. :)
