Just the cynic in me, but I wonder what percentage of these guys looking for a spot "for my kid/father/niece/grandma/dentist/war veteran/buddy who lives in a desert/etc, who's never caught a fish before and wouldn't think of keeping any" is actually just a guy who wants to know where the fish are biting so he can go fill a bucket.
I'm guessing it's 50-60%.
If you live near Stanley chapman Park normally has good action. Nothing big but consistent bite. Park at the beach area walk straight out about 50yds. If you have a fish finder drill holes until you find a depth of 10ft and you should catch fish all day.
You might be able to get enough bite action over off Sand Bar. I've had some luck there, but never any size to what I got. Perch and gills.
You'll have to walk down the hill cuz you can't drive under that bridge (you'll go through). I'd give um some business if you park in their lot.
