This has absolutely nothing to do with this thread.. We are having very low wind chills ( 0 - 1 ) for almost the next 48 hours. Our actual low will only be around 17 degrees. With some lovely participation on top of it. This is a tight structure, but we will see. At this writing we are holding in the 40's. I don't fret if temps are in the upper 20's for a short period..but it is those extended periods that do the damage.
Update this morning.... GH held at 34.8....more than happy with this all things considered
