I might have to take my daughters there this weekend.
For those interested in another good lake/pond for kids for "easy catch." There's also another place to consider.
Mout Baldy has two ponds, one pond with smaller trout and the second with some much larger fish. Never been to Jess Ranch but I have been to Mount Baldy. Keep in mind these are tiny ponds with clear water, so your kids can see the fish the whole time. My two cents is the Jess is the better deal in price from what I've read (Mout Baldy you pay per fish you catch). But if you want to guarantee your your son/daughter catches a big fish, he can see the fish the whole time, and you're willing to pay for it than Mount Baldy is the way to go.
