Photo of the Day (10.31.09)

Believe it or not, our Photo of the Day was taken in Kentucky -- at Mammoth Caves, to be exact. As Gadling photographer Peter Rivera explains, "A blast of arctic air flows up from the blackness. you go down concrete steps, lower and lower until the sunny August trees are left behind..." Peter aptly named this photo "descending into the abyss," and for those of you intrepid travelers who are venturing into the cool Halloween evening, I hope you come back from the abyss safely!

If you have some great travel shots you'd like to share, be sure to upload them to the Gadling pool on Flickr. We might just pick one as our Photo of the Day!
