Thanks to Eliot, who sent me this tip about grapes on Third Street. He also took the picture.

I’ve attached a cellphone picture I took this afternoon of  the Third
Street organic grape harvest (south side of the street between 7th and
8th Avenues, closer to 8th).  I’ve seen this harvest for the past few
years.  Yes, I’ve sampled the grapes and they are really good, but they
do have pits.
