http://www.holtonfarms.com/how-to-buy/farm-truck/Well, this is an interesting concept - Holton Farms in Vermont will be parking their new Farm Truck at Steinway and 35th Ave from 9-10 AM on Sundays.
They have a CSA option, but are also planning to have a retail option for "a la carte" purchases.
I'm excited about this - I liked the concept of the CSA but it didn't really fit my lifestyle when I tried. I always had too much leftover produce, even after splitting my share with friends. And outside of the local CSAs, finding super-fresh fruits and veggies in this area of Astoria (near Steinway/35th Ave) is a challenge, given how much trucking is involved in getting it into our grocery stores. There's the Union Square Greenmarket, but it's still a trek to lug everything home from there, even as a straight shot on the N/W train.
Sunday mornings are early, but... this could be worth it.
