Hi,
I rode Red Tail and SticknStones in May with a friend. There isn't a water tower that I remember but there is a parking lot at the top of Hurricane Mt Road.
From this lot we set out up the only trailhead from this lot. It's in the rear of the lot. There is signage that gets you onto the trail and headed towards
Red Tail Trail but the intersection where you pick Red Tail up is no longer marked. We were told the sign was blown down so we missed it at first.

I will make it easy for you; Red Tail is the only right hand turn you will see when headed up from that lot.
