If you are a builder or a creator in Second Life, this might be of interest to you. It's a hunt called Creative Christmas Hunt organised by Mandi Blanco.
It is a gridwide hunt going through a path of stores whose prizes are full perm items you may use in your creations. The starting point is at Christmas Lane (check the tracks on the floor with a Xmas tree, some of the stores have used them to guide hunters in the right direction). This Hunt has an in-world group called "Creative Christmas Gridwide Hunters". It is a very active, friendly and helpful group. For hints and the names of the participating stores check the Hunt blog. This Hunt lasts till December 22. Oh, and the object you are looking for is a small evergreen tree (see poster above). Happy Hunting!
