Back on Thursday (the 26th), we let First Son fish in the kitchen since it was so hot outside and we were feeling a little lazy. His fish makes a pretty big mess though. (When you catch it, the tail fin wiggles until you take it off the "hook.")
First Son will need to work on getting the fish off himself if he wants to go fishing for real. (In my family, you have to put your own worm on and take your own fish off. The cleaning and gutting can wait a little longer.)
