Personally I don't think Maxfield Parrish rates Crissy field, but opinions differ. But a nice big lot next to Lake Merrit seems about right.
Just because it's accessible doesn't make it inferior. Pre-Raphaelite art is also pretty heavy on the eye candy and nobody complains about that. Conversely it's not like you can't find any cheese in the De Young or other local museums - indeed my favorite painting there is rather conventional, an important factor in the heist I'm planning.
