My Carmine Jewel sour cherry tree outdid itself this year.
I bought stocks of Ballard Power years ago when hydrogen cells were going to be The Next Big Thing. Not many stocks thankfully, because it slipped further and further and then got delisted. It seems to be one of those things like airships that gets revived every 20 years or so.
At the moment my dream bike is the Circe Morpheus tandem. My better half started having balance problems a few years ago and had to give up riding after a long lifetime of cycling. He gets bored riding on a trainer indoors and wishes he could join me. In the front recumbent seat of the Morpheus, he would have a low center of gravity and a clear view. Unfortunately, the price is a bit more than we can afford, between currency exchange rates, shipping, and import duties.
