A common wildflower in the Western United States is the Trillium, sometimes known as the Western Wake Robin.    They are found in abundance in the woods south of our house, usually first appearing on the Ides of March.    This year I found the first one on March 17th.   It took nearly an hour of looking to discover only three flowers.   In another week or two, they will number in the hundreds, if not more.

We lost a dear friend and colleague, Terry White, K7TAU, in the spring of 2022.   Click on his photo to read about him.

By "Ultra-Portable," I mean transporting ham gear while on foot, or via bicycle or kayak, followed by putting the gear on the air.
