It's a sport that requires patients, a little know how and of course bait. California has a variety of fishing spots throughout the state and on Saturday they're inviting everyone to come out and take part. On July 1st, you won't need a fishing license if you plan on hitting your local fishing hole.
Now, there are some exceptions; there's a few fish that need people to carry a fishing report card and that list is on http://www.wildlife.ca.gov. The open fishing day allows people that otherwise wouldn't fish to come out and see what the state has to offer.
