definition, especially on its right side (our left). The definition is very sharp, I agree. Did you look at the pic I had a question about? It is not the same pic that you circled the pheromone chip & BF in. I posted the pic I wondered about in a post titled "This is", and I drew a red line around what I was asking about. I don't know what the scale is, so it may be nothing, or it may be a stump or something.
