To market to market...
Yandina markets are on saturday mornings and are great if you are looking for plants or old tools and some other second hand odds and ends (books included), but not all the produce is local farmer grown or organic. Some is, but best to ask where the produce comes from and whether chemicals are used if you are that way inclined.
Noosa Farmers Market on sunday is best for local grown and organic produce.
There is a nice Organic/gluten free cafe in Yandina, which also has bits and pieces inside and some old books for the kids to read.
A sunny day before the rains came again.
