I drove by a house today in Encinitas. It had a small pond in front with a sign that said Free fish. The house was on Melrose behind Juanitas Tacos. I did not get the address but it is a small street anyone that knows the area will know what I am talking about. It was on the west side of Melrose big Yellow sign you cant miss it. I was working and did not get out to see what they were. I assume Koi as it was in front of a house in a pond.
