O.K just a few days ago I bought my self a nice scientific anglers rod/reel/line combo and it works great. I was out on my front yard for an hour learning how to cast. Came back with numb fingers just 15 minutes ago. The first half I was casting great, but then my leaders loop started hitting the the snow on the ground, is this because my arms were starting to get tired or because of the cold weather. I couldn't see my line because it was dark out. help.
