Less than .5 mile from the interstate off ramp heading toward Sandstone falls, on your right, you will see a driveway crossing the tracks to a Citgo and Richmond's Store and Sandstone Sporting Goods.  Just further on, about 50 yards, there is a short guard rail on your left.  In winter you will see it.  In full bloom you will have to look for it.  It's just over the short length of guard rail.
