Rye, > I saw the following interesting signal this morning > around 182.2. > http://www.vais.net/~ryeg/Mystery.jpg This is a picture of migrating Dot-Birds. They only travel on the coldest nights, and are rarely seen. Strangely, their winter nesting ground is in Aitkin, MN. Go there, sometime. You'll see things that you can't see anywhere else.
