There is a wonderful farm in the very center of town called Collingwood Farm, complete with fields of vegetables and flowers, portable greenhouses, old farmhouse and farm stand. I find this absolutely amazing because in the hot market of 2007 this land of approximately 4-6 acres could have been sold off for any number of residences, or mixed use projects. This is one block from my home and a wonderful walk for me and my dogs. 
There is a large parcel on the corner for sale for $1,000,000 plus zoned for retail, mixed use of condos and stores.

The vegetables from Collingwood are fresh, organic and sold at the Saturday and Wednesday Port Townsend Farmers market, as well as the vegetable stand. Many times late at night I have stopped in at the farm stand which leaves its doors open 24 hours a day and has a payment jar using the honor system. There are fresh vegetables, flowers, jars of honey, sauces and organic coffee.
You know my town has a little produce stand with a jar and the honor system, I thought we must be alone in this world in having one. Glad to hear we are not.
We have so many Farmers' Markets here that I can't keep up with all of them. I do have my two favorites, though, that I stop by at on Thursdays and Saturdays.
Nothing like those crisp fresh vegetables in the supermarket. I am usually working during the markets, but we have the same produce in our Co-op. Lucky!
