There is street parking near ground zero, but if you're doing the entire YHunt PH series of caches you'll want to park near #1 or near #9.
Starting cache swag (all in a Ziploc bag): A log, 1" clamp, key tag, $1, barrette, spinning top, kaleidoscope, Spirograph Shrinky Dink and a plastic toy dog from All Dogs go to Heaven.
Happy Caching!
