Here in Central NY over the past 10 days we had 18 inches of snow, then temps shut up to mid fifties and had rivers of water shooting out of everywhere, then all froze solid, then we got another foot of snow or so... So I spent my days doing and re-doing the sets. Carried a bucket of Peat Moss with me and watched it all getting washed off during the thaw, covered by inches of snow, frozen solid after temps went back into the single digits. So, according to my observations Peat Moss hardens when temps drop into the single digits. The bag of peat moss was hard as a rock and I had to dig with the throwell to fill my trapline bucket.
I re-dug every set out and smacked the Duke footholds against the tree and they fired, then I cleaned them thoroughly and re-made the set... covered them back with fresh peat moss... pain in the arse...
