The light in the upper right, in the tree beside our outdoor hot tub, is a dripping icicle or meteor light (comes is a set of 12). It gives a really cool effect, the kind of thing where our guests say "What is that?". I have no financial interest in this but here is the link if you care.
The connection to Ultrarunning is that while I have hiked this winter in the snow, I have not yet dome any snowy trail running...a situation I hope to remedy real soon. However, that will take 2 ingredients: snow + motivation, so it may be awhile till said run happens.
