Weather will be perfect tomorrow!
I will be at the park entrance as early as 9:30 A.M. I'm an ugly tall guy wearing a black hat with a gray Tenba bag on my shoulder. Might be lugging a Bogen tripod. Still haven't decided on which cameras to bring.
I would recommend bringing snacks or lunch, plus a bottle or two of water.
There a great deli on W218 near Broadway. That's the place I usually load up on goodies before I enter the park.
