Good advice SEK, I also hit the rest & cams with a hair dryer, just be careful, too much heat can damage the string. If you ever hunt when it's sub zero I would be careful with the WD-40 or gun oil, it can freeze up. Liquid Graphite works great. I learned this lesson on a late Dec. ML hunt. I froze my yumpas off for 6 hours in sub zero weather, had about 4 inches of snow piled up in my lap by the time a nice 6x7 walked by. I was estatic until I went to take the shot and realized the trigger was frozen solid[&o]. Sometimes it's the little things that make the diff. in bagging that deer of a lifetime.
