Eternity.

I had the most amazing 2 hour hike along the coastal trail around Noosa today. There were some of the most spectacular views I have ever seen in my life. The weather was absolutely perfect, as well. By the time we got to Main Beach (the end), I felt like I was in a tropical rainforest, and we made sandcastles on the beach and drank smoothies.  This is my absolute favorite way to exercise, looking for dolphins and watching the surfers along the way.
