Increasing your options

I also learned that when reaching a T-junction, there were more than two choices – left and right, rather several: Was there an actual barrier? How big? Could I climb over it with ease? Could I under? Around? Stay there? Go backwards? Get in a helicopter and look at the options with a birds-eye view? Did I need to make the decision immediately? Or could it wait until I had more information? Suddenly, I had a multitude of options and more options were coming to mind……WOW, a T-junction will never look the same again.
