RE: Mild Winters?
Definitely wait. This weather may only be a temporary fluke (and is most likely). Next week in my area, temperatures are going to go back down to the mid 40s as highs. Mild winters like this are good for the game in the sense that they don't have to fight the cold obviously, access to food sources is much better and easier (don't have to dig through inches of snow and ice to get to anything consumable). The problem as far as growing is concerned is that this mild weather is bringing about unusuall changes in the environment that usally occur during the early spring (buds are shooting, flowers are starting to come out, I even saw a flock of geese flying north the other day), and like I said, this weather is can change in an instant (remember we are still in the heart of winter, and thus all it takes is a couple hard frosts and those blooming plants, etc are damaged and depending on the species and the conditions, they may not come back in the spring.
