The Arboretum has two exits in this area; the first one (which I used to use) is at the bottom of
a little rise about 500 feet back of the second one, which is about 500 feet from the intersection
with Loop 360. Unfortunately due to more inherent problems with frontage roads, this intersection
backs up bad enough that exiting traffic sometimes gets pretty crazy trying to get around the line
of cars waiting to turn left on NB 360.
