Non-Tillamook Ice cream

Hi

We used to be big Tillamook ice cream fans, but in the last few years have noticed a large drop in quality and have moved over to Umqua instead

We will be camping this weekend and I am looking for a shop that sells non+Tillamook ice cream between the town and let's say Lincoln City

Is this possible or is it all a company town, like you can't buy Pepsi in Atlanta?

Thanks
