I think I've been in Electric City once and frankly I think I blinked and missed it

I have been in this neck of the woods though. Lake Roosevelt is beautiful during the summer. When I was very young we went on a house boat and went up and down the lake in it.
Anyways, I have no specific comments about Electric City other than I doubt they are big enough to even garner a farmers market. It is very remote and has a true small town feel to it but it may be too small for you. Its one of those cities you have to go two towns over to get something.
If you want small cities close to that region I would recommend first and foremost Chelan, WA. Small city, with its own politics, beautiful, small tourism in the summer. Not annoying tourism. Its just a place many Washingtonians go to beat the rain, so most of it is exclusive to hotels or the downtown.
Ephrata is another choice. Small town, I believe has a small downtown with old shops and such close to Moses Lake (another choice too) for medical purposes.
Wennatche is a true town based off of farming that has grown into a city but still holds all of the old town feel.
A lot of the smaller towns in eastern washington around that area lack a remaining downtown, so I would be weary of some of the smaller cities unless that's really what you are looking for.
