Hi guys... The friend is me...
I spoke to a guy named Bill, director of power of the San Diego Argonauts. The spot here seems to be the Model Yacht Pond in Mission Bay. The problem: It's saltwater. Julian, wasn't pleased to hear that at all. Kinda scared me that my engine and boat were going to disintegrate on contact
Haha. However, my first boat and my first club is Puerto Rico, was running on saltwater.
The only other lake I'm aware of that that is freshwater, is Legg Lake, but unfortunately, that's 2 hours or more away.
There are other lakes closer, like Lake Hodges, but I doubt I'd be allowed to run my boat there. It's a like a state park or something.
Apart from that, Lake Dixon (too small and used for fishing) and Lake Calavera (a possibility, but probably too small). I don't think anybody runs boats there.
Going back to the model yacht pond... It's a good size, not choppy, you can walk all the way around it to retrieve your boat, and it's good picnic and grassy areas to hang out with the fam. But again, salt.
