comments,
- It\s entirely possible these are used as Christmas trees in Whoville.""After all, the tallest are just over two inches
- The name of the mountainous region where this photo was taken may make you think of Paris...""But we\re a little farther inland
- These organisms can sit dormant for lengthy periods, looking gray and lifeless.""Until the rain brings them back to life
- Another thing that seems to have sprung up in this region over the past few centuries is castles.""The place is lousy with them
