Maligator's pepper road trip is very impressive. My wife and I have been getting our peppers in the Yakima area. We leave around 5 or 6 am, and return early afternoon - but we take I90 and return back via I90, so I am extremely impressed with Maligator's pepper adventure.
My wife and I liked the Twisp farmers market. We had no problem finding parking across the street. Flow-wise, the market layout was interesting - basically a large "L" which results in people seeing any given exhibitor a couple times. There was a lot of variety of things to purchase which makes browsing interesting. Also, we enjoyed the live music - haven't seen that in any other farmers market we've been to in the Seattle area. Size of the market was on the medium+ range - bigger than most we've been to, but not the largest. If I recall correctly, only the Yakima farmers market is bigger, or it seems that way. Overall, we liked the Twisp farmers market, and would go again. The only thing I can suggest is to have the market open longer - I think it closes at noon or 1 pm.
