Geotripper shared a picture of a lovely, Middle-Earthish tree in the midst of Yosemite Park, while Clastic Detritus showed a picture of some Brushy Canyon vintage Madrone, so I reckon I'll just share a picture of my favorite tree: The Juniper.
I like junipers for two reasons. One, if you see them, then you are Probably somewhere close to some good rocks, which is always good news.
Second, I like Junipers because you can make gin from their berries.
Junipers: are they the best trees? They just might be.
EDIT: Holy Smokes! So Many Pictures of Trees!
