Some people have better luck following these:
Locals: Going from the Grey Eagle to 12 Bones turn RIGHT BEFORE the R/R tracks, you are now at the lower level of Wedge Studios.
Everyone Else: Find the corner of Patton and Clingman, turn at the traffic light to go down the hill (Clingman) turn LEFT at the Grey Eagle, at the bottom of the hill, take Clingman Ext. to 5 way stop, turn RIGHT toward the R/R tracks, turn right BEFORE the tracks, if your on a dirt parking lot, you found it! Park somewhere!
