So Dawn went and submitted the paperwork for the perk test, and you'll see the running cost at the bottom updated as such. The cost in our county is $350 per site (though they generally poke several holes in the general area).
We're so close to the county line that we could almost throw a rock into the next county. Their cost for a perk test? $50.
Man, we got ripped off!
