Radon Supplement.

Article on radon from kstp and a few more pictures of the install.  I drilled the hole into the concrete and was lucky to come in right by the drain tile.  I drilled a few more holes in the drain tile to increase airflow to the rest of the basement.

I also put a cap on the vent coming out of the roof, however it did reduce the airflow (from what I could see on the manometer).
