This is a fun family event for kids, adults, etc.
Balboa lake has lots of Carp, Catfish, Tilapia etc. All you need is a cheap pole, 1/2 oz weights, size 8 single hooks, and either corn, corn tortillas, or earth worms.
We will meet at Balboa park. If you are facing the waterfall, we will be to the right of it, and down the shore about 150 feet near the trees.
Adults need a CA fishing license, kids under 16 do not.
The kids will probably catch Tillapia, and they will range from 2" to 12" in length. The adults may want to go for the larger carp and catfish, although any opportunity to wet a line is fun ;).
Things to bring:
Pliers or hemostat
Cooler: something to eat and drink.
There are bathrooms (about a couple hundred yards away or more).
This is reclaimed water so I would advise not to eat the fish. The kids will have a blast catching fish though.
