Sourdough Starter

I am going to start a sourdough starter before Autumn sets in so I can bake some yummy bread during the colder months.... I will post a link to the recipe that I am using, but I would greatly appreciate it if anyone out there could give me pointers on this sort of thing. I know a true sourdough connoisseur would never use yeast to make their starter, but unfortunately I live in an area that even professional pastry chefs have to use a little yeast to kick start their sourdough starter because there isn't enough wild yeast in the air in Oregon.

Here is the link to the sourdough starter recipe that I will be using...
