Ed is what people call me and my spouse doesn't like it at all. Since he was eighteen he's been operating as an info officer but he plans on changing it. For a while I've been in Alaska but I will have to transfer in a year or two. What me and my family members love is to climb but I'm considering on starting some thing new.
