It is amazing how folks will lock in 7 to 10 day temps but throw shade on other 7 to 10 day products. I understand temps are easier to predict but in "Sping" it's a crapshoot with that pond being in the 40s and deep snow cover to our North. However if we get lots of sun with downslope and dry soils temps can skyrocket. I just am skeptical until we see the whites of its eyes.
