Lots of friendly camera sharing/trust in you take mine/I'll take yours. (NOT in NY!) Bring Publix bags to sit on (damp earth, clayish) & get a bunch of food samples from food tents along Basin & eat in Blossom yard behind food tent area. There's music close by and you are having the most scenic picnic of your life. Walking in this yard was dreamy/I cried it was soo beautiful. You can spin in a circle and are just overwhelmed by all those trees. This area was way better than walking along the Basin sidewalk. Never did find a good taxi pick up point... They'll drop ya, but won't pick up along street.
