Lurking in the shadows of the famous Heart Attack Hill is the Aneurysm Bypass. When one hears the word bypass, an immediate reaction might be, "Oh, it must be easier." Well...not quite. This "bypass" has multiple challenging spots that will test any stock or mildly built rig. The loose rock and the tall, protruding boulders give Heart Attack Hill a run for its money on which is the more difficult ascent up Kelly Flats. Some say it's easier than Heart Attack Hill, and some say it's harder... I guess you will just need to run it to find out.
