It turned out to be a bit more of an adventure than the average rest stop.  It started with a steep 14% grade on a winding two lane road.  Ok, that’s doable.  Then the real object of the stop. Tonto Natural Bridge SP.  This was a chance to see a big travertine natural bridge.  Of course, we had to see it from below.  To the trails!  We climbed among boulders, that was cool.  But then, we came across the “slick rock”.  It was polished sooo smooth and with curves that were poised to launch climbers off into the pools below.  I must say, there were a few tense moments; but in the end all is well.  We got to see a magnificent example of Mother Nature’s handiwork and managed to get no wetter than the splashes from the waterfall overhead.  We definitely stretched our legs.
