Dry falls is anything but Dry. There is a steady mist in the air anywhere near the falls. You can walk behind this falls wihtout really getting wet, other than the mist and a few drips. Getting a good (and dry) angle to take decents shots is a challenge.
From Highlands, proceed 3.3 miles on US 64 toward Franklin. Look for National Forest signs on the left indicating something of interest ahead. The signs are obscured by the railing, and the steep pull-offs into the parking lot are not obvious. Parking is only $2 and follow the short path down to the falls.
These shots were all taken with a Canon 20D and 24-70L Lens using a B+W ND103 and B+W CP mounted on a Bogen 3021Pro tripod and using a Bogen 322RC2 Ball/Grip head.
I rate this falls at 6-7 and access difficulty at 2.
