I have been hired to make a welcome cake for a new Dr. Starting at our hospital. The hospital has asked me to make something that incorporates his hobbies.....which are, hiking, fishing, hunting, mountain biking. This will be a full sheet cake and the layers are baked and in the freezer. Does anyone have an idea as to what or how to decorate. My brain is not coming up with anything.

How about using blue piping gel to make a lake on one side of the cake. On the other side, use rice krispy treats to shape a mountain and decorate with icing. If you like making figures, you could make a man sitting at the edge of the lake fishing, maybe with a bicycle, rifle, and hiking pack next to him.
