Rayproado714, congratulations on your Perris triumph. I have fished Perris a few times over the past month or so with very little success. I hope it will become a regular go-to; but, right now I am boycotting them because they won't honor my Senior pass between now and Labor Day (not Perris's fault. Came from Sacramento and surprised the staff out there.) I note the Prado in your user name. It is right around the corner from me, but I will not pay the exorbitant $23/day fee to launch my yak and fish in that pond.
So, the bays. I lover everything about them but the drive from Corona. It helps if I start before 5Am. Like everyone else, I have caught a few exotics. That is part of the charm.
I may be naive, but I don't feel any sense of danger at all in these bays. Not compared to the fast rivers I started 'yaking on. Well, let me qualify that--power boats. But, you don't have to venture into their channels if you choose not to; and they aren't as scary as some of the cowboys at Perris.
I fish from a kayak, and I am a terrible fisherman. But, if you can't hook up with a knowledgeable tuber, I would be happy to show you around some of the bays. I typically fish Alamitos or Huntington Harbor. Occasionally Newport during the week when I can work around the mob scenes. Actually, I mostly fish during the week, but lately am doing some Saturdays when family commitments don't take precedence. Never on Sunday. If you are desperate for company, give me a shout, and we can try to work it out. (I owe some pay forward for guys on this forum who have accepted a 'yaker, and generously helped me.)
One late thought. Float tubers in the bays have to be much more aware of the tides and winds than I do. Bottom line, if possible, it would be to your advantage to learn from those who are tuned into that aspect of tubing the bays. I can show you the geography, but cannot intelligently discuss your limits.
BTW, I found this site though the videos posted on Youtube by OrneryBob. You can google them OB has put out quite a bit of information about launch sites, etc. on various bays.
